If you can, pick a second gig that doesn’t look anything like your nine-to-five job. If you sit at a computer all day, for example, don’t become a transcriptionist or pick up work as a virtual assistant. You might be more energized getting on your feet working in a boutique or out walking dogs. Remember that variety is the spice of life, even when it comes to making a little extra money, and don’t assume that the most lucrative side gig is the best fit for you. The best side gig is one you can tolerate and even enjoy doing for as long as you want to rake in those extra bucks.
