When you’re constantly traveling from class to class, your book bag or purse holds a lot of stuff: tissues, ChapStick, an extra hoodie, your wallet and student identification card, a phone, flash drives, snacks, gum, a water bottle, miscellaneous pens and highlighters—and probably a lot more. All that clutter weighs you down both physically (your shoulders and back might even be hurting lately from lugging around a heavy bag every day!) and mentally. It’s true: studies have found that physical clutter overloads your senses and serves as a distraction, leading to stress, foggy thinking, and poor performance. Whether you’re throwing things in your bag “just in case” or you’re truly in need of each item on a day-to-day basis, every once in a while, clean out what you carry to start fresh. Get tidy so you can truly focus on that philosophy paper.
