how do i spend a day on weekend i am a student.i spend 7.5 hours on practicing and learning new thing. i spend 3 hours on searching reading materials on internet and books.i sleep from 11:20pm to 8:50am , so it is 9.5 hours ,proper rest can help brain work better,i don't think 9.5 hours is too many for sleeping.So I still have 4hours, i can entertain or eat on this four hours. i divide 7.5 hours into 0.5+1+2+4 hours. 0.5hours for recording life and reacting plan 1 hour for bodybuilding and exercising. 2hours for reading paper and learning online course. 4hours for reading book and doing homework. i think this is an effective way to distribute a day, every part of time like fragment,so become controllable. 3 hours of material searching also help me more effective on learning
