Income seldom exceeds personal development.

Things that I felt absolutely sure of but a few years ago, I do not believe now. This thought makes me see more clearly how foolish it would be to expect all men to agree with me.

The difference between where you are today and where you'll be five years from now will be found in the quality of books you've read.

Success is nothing more than a few simple disciplines, practiced every day; while failure is simply a few errors in judgment, repeated every day. It is the accumulative weight of our disciplines and our judgments that leads us to either fortune or failure.

It's important to learn from your mistakes, but it is BETTER to learn from other people's mistakes, and it is BEST to learn from other people's successes. It accelerates your own success.

Your life, my life, the life of each one of us is going to serve as either a warning or an example. A warning of the consequences of neglect, self-pity, lack of direction and ambition... or an example of talent put to use, of discipline self-imposed, and of objectives clearly perceived and intensely pursued.

You can't hire someone else to do your push-ups for you.
