IT is not easy question. I dont think that exist 100 pecent method. But.
1) Do SPORTS!
2) Have a walks and some relax nothing to do intervals
3) play videogames you like
4) Some village time! Go to the village, if you have for weekend
5) learn new skills you need. Programming, art, music
6) practice
Everytime you practice some things become more easy! And thats the trick to do the things that you have skills to do. In theory... Of course everybody just starts what they want, and they dont have enough skills... and lost motivation yes... so go to point 1.!!!!!!
