This is more likely for a 9-5er, but it happens to artists too. I love drawing digitally for client projects, but it's not the same as drawing cool stuff just for fun by hand. Also, with fall in swing and winter coming, we all need to be reminded to get out of the apartment more! Freelancers, please get outside for some fresh air at least once a day, even if it's crappy weather outside. You'll feel the difference.
