I gave this advice to a young brother who asked me the keys to my "success"(I say this humbly, of course). I thought I would share:
1) Educate the hell out of yourself - learning is a lifelong process.
2) Think a lot so you can create and develop your own mind, and not somebody else's.
3) Work as hard as you can every single day, year round.
4) Keep the bullsh*t out of your life...it ends up wasting your time.
