24 hours per day is surely too short.
6 a.m. - get up
6:30 a.m. - leave to work
8:00 a.m. - work, and browse random websites when bored
5:30 p.m. - come off work
7:00 p.m. - get home
... (eat, rest, clearn, blahblah..)
around 0 a.m. - go to bed
There's not much left for multiple hobbies.
It seems I spend to much time on the bus (3 hours or so), maybe I should try to read or learn something useful during that.
