We live in a vague world. And it gets vaguer all the time. In this environment, the power of the specific, measurable and useful promise made and kept is difficult to overstate.

If not enough people doubt you, you're not making a difference.

My problem with the search for the badge of real is that it trades your goals and your happiness for someone else's.

You have brilliance in you, your contribution is valuable, and the art you create is precious. Only you can do, and you must.

Teaching young people to sell is a priceless gift.

Not changing your strategy merely because you're used to the one you have now is a lousy strategy.

The easier it is to quantify, the less it's worth.
