Set excellent performance as your standard and strive to achieve it each day

Circumstances do not make the man or woman, they merely reveal them.

The predominant quality of successful people is optimism.... Your level of optimism is the very best predictor of how happy, healthy, wealthy, and long-lived you will be.

All the businesses from the beginning of history have struggled with product development (assuming there is a market, doing the market testing and so on). But now they start with customer development. Get the customer who says, "Yes. I want that. I need it. I wanna use it. I'll pay for it." And then you go back and work with your engineers. It is changing the world!

Happiness and self-confidence come naturally when you feel yourself moving and progressing toward becoming the very best person you can possibly be.

Nobody works better under pressure. They just work faster.

The success you are enjoying today is the result of the price you have paid in the past.
