Motivation. Yeah.* You gotta do what motivates you, even if it's
   something that other people say, "HEY YOU'RE WASTING YOUR
   TIME!"* F'them.* If you don't mind what you're doing, then keep
   doing it until you get bored of doing it, then do something
   else.* Napping is good too.* When I go to sleep I tell myself,
   "YOU ARE GOING TO HAVE AN AMAZING REVELATION WHEN YOU WAKE
   UP!"... and... weirdly enough, it works. So I keep paper and pen
   by my bed. THis way I don't need motivation; my unconscious
   brain does all the hard work, and I get to sleep through it :P
