As a kid from Compton, you can get all the success in the world and still question your worth.

I look at where I'm at today and realize that most of my success is owed to the mentors that was in my life.

I've often felt there might be more to be gained by studying business failures than business successes.

I failed my way to success.

Anything that won't sell, I don't want to invent. Its sale is proof of utility, and utility is success.

The first requisite of success is the ability to apply your physical and mental energies to one problem without growing weary.
