Yeah, I've got ideas.
My supervisor at my old job which I will be taking back soon was one of the most SUCCESSFUL people I know, when it came to grades, fitness, money, and the ladies ALL because he followed some simple steps. He seriously just budgeted his time REALLY well, and was able to turn himself ON and OFF when it came to Work/Play. During the week, he STUDIED, WORKED, and EXERCISED. That's it. He didn't let distractions like Facebook and such get in the way. He did his homework the day it was assigned.
I know very few people who can work hours and make good money, exercise faithfully enough to maintain a six pack, and still find ONE day a week to party and get drunk. But this guy did it, just with time budgeting and discipline. That can be you man!
