Find your true self. The old question, asked in many ages, "Who am I?" Once you figure out who am I, and you know who am I, then you have that knowledge of self.
RZAThere's strong men of wisdom in many different fields. They say 5% of the people are wise and righteous and 10% are wise but use their wiseness for wickedness or to deceive others. It's like a magician: he knows the answer to the trick, but you don't. He has to keep you blind to the truth in order for the illusion to work. When you've got that kind of wisdom and somebody else doesn't, you can always take advantage of them.
RZADo the knowledge, meaning: look, listen, observe, and also respect. If you do that, you'll have a strong foundation to build anything you want to do in life upon. Know before you do. Look before you leap. And if you want to follow in my footsteps, make sure you step in the ones that went in the right direction.
