"When you want to succeed as much as you want to breathe, that's when you'll be successful."
"Most of you say you want to be successful, but you don't want it bad....you just kinda want it. You don't want it badder than you want to party. You don't want it as much as you want to be cool. Most of you don't want success as much as you want to sleep."
"Don't cry to give up, cry to keep going."
