Time and energy. I used to exercise a lot. Last year I ran a mile a day and this year I was going to the gym three times a week and regularly played basketball after work. However when I got back home after a workout, all I could do was sit down and relax for the rest of the evening. I didn't have the energy to get behind the computer and work on any side projects. For the past two months I've given up exercise for multiple side projects. I'll probably switch back again since I tend to get anxiety and the only cure for it has been running.
