I would agree with the Sugarless - to do lists are good (I used to survive on them when I was about 10 - made one every night, they are very satisfactory )
Routine is also good - I'm messing mine up at the minute but when I stick to it I feel really good. Hobbies and to do lists can be fitted into this and I've found that what I've always liked about work/school is the routine, and I think a lot of other people would agree.
Good luck finding a solution.
