I think it's best to have a useful form of procrastination. There was this one guy who became productive THROUGH procrastination, it was on an article somewhere, so trippy, he had this awful task to do and so procrasinated that by doing all these other things that comparatively were better.
Right now I'm procrastinating doing computer science courses online and reading books related to it. Also can say it's close enough to my last game, SDD so it's fine
Most common - Easy, BoS
Most random - There are a few, but a couple weeks ago I found myself reading legal cases from Florida in the early 1990's. If I can think of any other randoms I will add them to the list.
Procastination is the best, I swear I need it to work effectively (not joking).
I was bored the other day at around 10am or so. Intended to go for a walk for half an hour or so. Walked for an hour and thought, hmm, lets see how far I can walk. Walked for 3 more hours, got lunch, then walked for another couple of hours before then catching public transport back to where I started from. Then that was the day gone.
