The only thing we know about the future is that it will be faster changing and more unpredictable than the present.

Do your own market research; ask your last ten customers exactly why they bought from you.

Every great leap in life comes after you have made a clear decision of some kind.

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!

Whenever you complete a task of any size or importance, you feel a surge of energy, enthusiasm, and self-esteem. The more important the completed task, the happier, more confident, and more powerful you feel about yourself and your world.

The greatest enemies of success and happiness are negative emotions of all kinds.

Define your goals in terms of the activities necessary to achieve them, and concentrate on those activities.
