Notes

Introduction

“In my retiring room”; “I keep the key”; and “The feeling of repose and renewal”: Jung, Carl. Memories, Dreams, Reflections. Trans. Richard Winston. New York: Pantheon, 1963.

“Although he had many patients” and other information on artists’ habits: Currey, Mason. Daily Rituals: How Artists Work. New York: Knopf, 2013.

The following timeline of Jung’s life and work also proved useful in untangling the role of deep work in his career: Cowgill, Charles. “Carl Jung.” May 1997. http://www.muskingum.edu/~psych/psycweb/history/jung.htm.

Anders Ericsson from Florida State University is a leading academic researcher on the concept of deliberate practice. He has a nice description of the idea on his academic website: http://www.psy.fsu.edu/faculty/ericsson/ericsson.exp.perf.html.

My list of the deep work habits of important personalities draws from the following sources:

“A 2012 McKinsey study found that”: Chui, Michael, et al. “The Social Economy: Unlocking Value and Productivity Through Social Technologies.” McKinsey Global Institute. July 2012. http://www.mckinsey.com/insights/high_tech_telecoms_internet/the_social_economy.

“What the Net seems to be doing is” and “I’m not the only one”: Carr, Nicholas. “Is Google Making Us Stupid?” The Atlantic Monthly, July–August 2008. http://www.theatlantic.com/magazine/archive/2008/07/is-google-making-us-stupid/306868/.

The fact that Carr had to move to a cabin to finish writing The Shallows comes from the Author’s Note in the paperback version of the book.

• “Why Use Stata.” www.stata.com/why-use-stata/.

The SQL example I gave was from postgreSQL, an open source database system popular in both industry and (especially) academia. I don’t know what specific system Silver uses, but it almost certainly requires some variant of the SQL language used in this example.

The Principle of Least Resistance

“At first, the team resisted”; “putting their careers in jeopardy”; and “a better product delivered to the client” as well as a good summary of Leslie Perlow’s connectivity research can be found in Perlow, Leslie A., and Jessica L. Porter. “Making Time Off Predictable—and Required.” Harvard Business Review, October 2009. https://hbr.org/2009/10/making-time-off-predictable-and-required.

Allen’s fifteen-element task management flowchart can be found in Allen, Getting Things Done, as well as online: http://gettingthingsdone.com/pdfs/tt_workflow_chart.pdf.

Busyness as a Proxy for Productivity

The h-index for an academic is (roughly speaking) the largest value x that satisfies the following rule: “I have published at least x papers with x or more citations.” Notice, this value manages to capture both how many papers you have written and how often you are cited. You cannot gain a high h-index value simply by pumping out a lot of low-value papers, or by having a small number of papers that are cited often. This metric tends to grow over careers, which is why in many fields h-index goals are tied to certain career milestones.

“To do real good physics work”: comes around the 28:20 mark in a 1981 TV interview with Richard Feynman for the BBC Horizon program (the interview aired in the United States as an episode of NOVA). The YouTube video of this interview that I watched when researching this book has since been removed due to a copyright complaint by the BBC (https://www.youtube.com/watch?v=Bgaw9qe7DEE). Transcripts of the relevant quote, however, can be found at http://articles.latimes.com/1988-02-16/news/mn-42968_1_nobel-prize/2 and http://calnewport.com/blog/2014/04/20/richard-feynman-didnt-win-a-nobel-by-responding-promptly-to-e-mails/ and http://www.worldcat.org/wcpa/servlet/DCARead?standardNo=0738201081&standardNoType=1&excerpt=true.

The Cult of the Internet

Alissa Rubin tweets at @Alissanyt. I don’t have specific evidence that Alissa Rubin was pressured to tweet. But I can make a circumstantial case: She includes “nyt” in her Twitter handle, and the Times maintains a social media desk that helps educate its employees about how to use social media (c.f. https://www.mediabistro.com/alltwitter/new-york-times-social-media-desk_b53783 ), a focus that has led to more than eight hundred employees tweeting: https://twitter.com/nytimes/nyt-journalists/members.

Here is an example of one of Alissa Rubin’s articles that I encountered when writing this chapter: Rubin, Alissa J., and Maïa de la Baume, “Claims of French Complicity in Rwanda’s Genocide Rekindle Mutual Resentment.” New York Times, April 8, 2014. http://www.nytimes.com/2014/04/09/world/africa/claims-of-french-complicity-in-rwandas-genocide-rekindle-mutual-resentment.html?ref=alissajohannsenrubin.

Execute Like a Business

“How do I do this?”: from pages xix–xx of McChesney, Chris, Sean Covey, and Jim Huling. The 4 Disciplines of Execution. New York: Simon and Schuster, 2004.

Clayton Christensen also talks more about his experience with Andy Grove in a July–August 2010 Harvard Business Review article, “How Will You Measure Your Life?” that he later expanded into a book of the same name: http://hbr.org/2010/07/how-will-you-measure-your-life/ar/1.

Be Lazy

“I am not busy” and “Idleness is not just a vacation”: Kreider, Tim. “The Busy Trap.” New York Times, June 30, 2013. http://opinionator.blogs.nytimes.com/2012/06/30/the-busy-trap/.

Much (though not all) of the research cited to support the value of downtime was first brought to my attention through a detailed Scientific American article on the subject: Jabr, Ferris. “Why Your Brain Needs More Downtime.” Scientific American, October 15, 2013. http://www.scientificamerican.com/article/mental-downtime/.

“The scientific literature has emphasized”: from the abstract of Dijksterhuis, Ap, Maarten W. Bos, Loran F. Nordgren, and Rick B. van Baaren, “On Making the Right Choice: The Deliberation-Without-Attention Effect.” Science 311.5763 (2006): 1005–1007.

The attention restoration theory study described in the text: Berman, Marc G., John Jonides, and Stephen Kaplan. “The Cognitive Benefits of Interacting with Nature.” Psychological Science 19.12 (2008): 1207–1212.

I called this study “frequently cited” based on the more than four hundred citations identified by Google Scholar as of November 2014.

An online article where Berman talks about this study and ART more generally (the source of my Berman quotes): Berman, Marc. “Berman on the Brain: How to Boost Your Focus.” Huffington Post, February 2, 2012. http://www.huffingtonpost.ca/marc-berman/attention-restoration-theory-nature_b_1242261.html.

Rule #2

My estimate of “hundreds of thousands” of daily Talmud studiers comes from an article by Shmuel Rosner, “A Page a Day,” New York Times, August 1, 2012 (http://latitude.blogs.nytimes.com/2012/08/01/considering-seven-and-a-half-years-of-daily-talmud-study/), as well as my personal correspondence with Adam Marlin.

“So we have scales that allow us to divide” and “The people we talk with continually said”: Clifford Nass’s May 10, 2013, interview with Ira Flatow, on NPR’s Talk of the Nation: Science Friday show. Audio and transcript are available online: “The Myth of Multitasking.” http://www.npr.org/2013/05/10/182861382/the-myth-of-multitasking. In a tragic twist, Nass died unexpectedly just six months after this interview.

Work Like Teddy Roosevelt

The general information about Theodore Roosevelt’s Harvard habits comes from Edmund Morris’s fantastic biography: Morris, Edmund. The Rise of Theodore Roosevelt. New York: Random House, 2001. In particular, pages 61–65 include Morris’s catalog of Roosevelt’s collegiate activities and an excerpt from a letter from Roosevelt to his mother that outlines his work habits. The specific calculation that Roosevelt dedicates a quarter of his typical day to schoolwork comes from page 64.

“amazing array of interests”: from page 64 of Morris, Rise of Theodore Roosevelt.

The positive receipt of Roosevelt’s book by the Nuttall Bulletin comes from Morris’s endnotes: in particular, note 37 in the chapter titled “The Man with the Morning in His Face.”

“one of the most knowledgeable”: from page 67 of Morris, Rise of Theodore Roosevelt. I ascribed this assessment to Morris, though this is somewhat indirect, as Morris here is actually arguing that Roosevelt’s father, after the publication of The Summer Birds of the Adirondacks, must have felt this about his son.

“The amount of time he spent at his desk”: from page 64 of Morris, Rise of Theodore Roosevelt.

Memorize a Deck of Cards

Quotes from Daniel Kilov came from personal correspondence. Some background on his story was taken from his online biography, http://mentalathlete.wordpress.com/about/, and Lieu Thi Pham. “In Melbourne, Memory Athletes Open Up Shop.” ZDNet, August 21, 2013. http://www.smartplanet.com/blog/global-observer/in-melbourne-memory-athletes-open-up-shop/. More on Kilov’s scores (memory feats) from his two medal-winning championship bouts can be found on the World Memory Statistics website: http://www.world-memory-statistics.com/competitor.php?id=1102.

For more interesting connections between memorization and general thought, see: The Art of Memory, by Frances A. Yates, which was first published in 1966. The most accessible version seems to be the handsome 2001 reprint by the University of Chicago Press.

Rule #3

“the most connected man in the world”; “I was burnt out”; “By the end of that first week”; “The end came too soon”; and general information about Baratunde Thurston’s experiment: from the Baratunde Thurston article “#UnPlug” that appeared in the July–August 2013 issue of Fast Company. http://www.fastcompany.com/3012521/unplug/baratunde-thurston-leaves-the-internet.

The reference to Thurston’s Twitter usage refers to the tweets on March 13, 2014, from the Twitter handle @Baratunde.

“Entertainment was my initial draw”; “[When] I first joined”; and “[I use] Facebook because”: drawn from comments sections of the following two blog posts I wrote in the fall of 2013:

• “Why I’m (Still) Not Going to Join Facebook: Four Arguments That Failed to Convince Me.” http://calnewport.com/blog/2013/10/03/why-im-still-not-going-to-join-facebook-four-arguments-that-failed-to-convince-me/.

Apply the Law of the Vital Few to Your Internet Habits

“Who says my fans want to hear from me”: from a Malcolm Gladwell talk that took place at the International Digital Publishing Forum as part of the 2013 BookExpo America Convention, held in May 2013, in New York City. A summary of the talk, including the quotes excerpted in this chapter, and some video excerpts, can be found in “Malcolm Gladwell Attacks NYPL: ‘Luxury Condos Would Look Wonderful There,’” Huffington Post, May 29, 2013. http://www.huffingtonpost.com/2013/05/29/malcolm-gladwell-attacks-_n_3355041.html.

“I don’t tweet” and “It’s amazing how overly accessible”: from the following Michael Lewis interview: Allan, Nicole. “Michael Lewis: What I Read.” The Wire, March 1, 2010. http://www.thewire.com/entertainment/2010/03/michael-lewis-what-i-read/20129/.

“And now, nearly a year later”: from “Why Twitter Will Endure,” by David Carr for the New York Times in January 2010: http://www.nytimes.com/2010/01/03/weekinreview/03carr.html.

“Twitter is crack for media addicts”: from an online opinion piece written for the New Yorker website: Packer, George. “Stop the World.” The New Yorker, January 29, 2010. http://www.newyorker.com/online/blogs/georgepacker/2010/01/stop-the-world.html.

The law of the vital few is discussed in many sources. Richard Koch’s 1998 book, The 80/20 Principle (New York: Crown, 1998), seems to have helped reintroduce the idea to a business market. Tim Ferriss’s 2007 mega-seller, The 4-Hour Workweek (New York: Crown, 2007), popularized it further, especially among the technology entrepreneur community. The Wikipedia page on the Pareto principle has a good summary of various places where this general idea applies (I drew many of my examples from here): http://en.wikipedia.org/wiki/Pareto_principle.

Quit Social Media

“Everything’s more exciting when it’s a party” and general information on Ryan Nicodemus’s “packing party”: “Day 3: Packing Party.” The Minimalists. http://www.theminimalists.com/21days/day3/.

Average number of Twitter followers statistic comes from: “Average Twitter User Is an American Woman with an iPhone and 208 Followers.” Telegraph, October 11, 2012. http://www.telegraph.co.uk/technology/news/9601327/Average-Twitter-user-is-an-an-American-woman-with-an-iPhone-and-208-followers.html.

Take this statistic with a grain of salt. A small number of Twitter users have such a large following that the average skews high. Presumably the median would be much lower. But then again, both statistics include users who signed up just to try out the service or read tweets, and who made no serious attempt to ever gain followers or write tweets. If we confined our attention to those who actually tweet and want followers, then the follower numbers would be higher.

Don’t Use the Internet to Entertain Yourself

“Take the case of a Londoner who works”; “great and profound mistake”; “during those sixteen hours he is free”; and “What? You say that full energy”: from Chapter 4 in Bennett, Arnold. How to Live on 24 Hours a Day. Originally published in 1910. Quotes are from the free version of the text maintained in HTML format at Project Gutenberg: http://www.gutenberg.org/files/2274/2274-h/2274-h.htm.

Conclusion

“a prodigious feat of concentration”: from an article for the Harvard Gazette: Isaacson, Walter. “Dawn of a Revolution,” September 2013. http://news.harvard.edu/gazette/story/2013/09/dawn-of-a-revolution/.

“The one trait that differentiated [Gates from Allen] was focus”: Isaacson, Walter. The Innovators. New York: Simon and Schuster, 2014. The quote came from 9:55 into Chapter 6 of Part 2 in the unabridged Audible.com audio version of the book.

The details of the Bill Gates story came mainly from Isaacson, “Dawn of a Revolution,” article, which Walter Isaacson excerpted (with modification) from his Innovators. I also pulled some background details, however, from Stephen Manes’s excellent 1994 business biography. Manes, Stephen. Gates: How Microsoft’s Mogul Reinvented an Industry—and Made Himself the Richest Man in America. New York: Doubleday, 1992.
