I'm finding that only by excelling at your studies you can be truly at peace with your life and your conception of self. Maybe that's just me, but we all desperately want to be as special as we were once told we were.
There's no substitute for simply going for it. An hour a day, two - build up to what you find comfortable.
Try to have fun with your studies and always go that extra mile.
That being said, I'm going to the library to kick some Ancient Greek ass.
