I use the time for all kinds of productive things. I go to the gym, take care of my daily emails, run quick errands. Anything I can do w/ the app on in case a request comes through but that I need to do anyway. This week is still Christmas break and I've been online about 15 hours for only $50 in earnings....BUT I've spent 3 hours at the gym, run 5 or 6 errands and worked 6.5 hours at my very PT job. Maximizing that dead time is an absolute necessity. When students are here and I might only have 10 minutes between rides instead of an hour or two I do work on my laptop, practice language skills on Duolingo and take surveys for money.
