What you concentrate on largely determines the quality and quantity of the results that you get and the success that you enjoy.

I believe the greatest successes you will ever attain are still waiting for you on the road ahead.

You are fully responsible for everything you are, everything you have and everything you become.

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!

You can get control of your tasks and activities only to the degree that you stop doing some things and start spending more time on the few activities that can really make a difference in your life.

Decide upon your major definite purpose in life and then organize all your activities around it.

When you start doing what you love to do, you will never work another day in your life.
