To succeed in this new world, we will have to learn, first, who we are. Few people, even highly successful people, can answer the questions, Do you know what you're good at? Do you know what you need to learn so that you get the full benefit of your strengths? Few have even asked themselves these questions.

The definition of success--To laugh much; to win respect of intelligent persons and the affections of children; to earn the approbation of honest critics and endure the betrayal of false friends; to appreciate beauty; to find the best in others; to give one's self; to leave the world a little better, whether by a healthy child, a garden patch, or a redeemed social condition.; to have played and laughed with enthusiasm, and sung with exultation; to know even one life has breathed easier because you have lived--this is to have succeeded.
The more successful enterprises are the more they try to replicate, duplicate, codify what makes us great. And suddenly they're inward thinking. They're thinking how can we continue to do what we've done in the past without understanding that what made them successful is to take risks, to change and to adapt and to be responsive. And so in a sense success breeds its own failure. And I think it's true of a lot of successful businesses.
