I currently work full time and do full time uni, so my time is stretched as far as it can go. I've sat down an analysed my productivity over the day and noted that from when I finish work at 5 or 6 until after I finish having dinner at around 8-8.30 I rarely get anything done, I try, but end up being distracted. So I decided to write that time off, and go do exercise to refresh myself for the late night stint. I always used the excuse that if I'm going to be up really late tonight working, how can I justify half an hour of exercise, but once you sit down and be honest with yourself you'll realize that you waste many half-hours being distracted/on HN/Facebook etc, and those half-hours don't have the benefits that exercise does.
