My process:
1. Sleepy? Sleep
2. Not Sleepy? Surf the wonders of internet, play eroge/vn, read manga until sleepy
On some occasion, such as a very interesting games, my sleep switch is gone, and can stay awake until I feel satisfied with the game progress.
Now I am aware of the importance of time, so I try not to waste it...
Though most of my effort is in vainXD
All right, play games, surf online aimlessly, go to SNS sites, and do exercises
