There's no abiding success without commitment.

You can make a lot of money. You can rule kingdoms or run huge businesses or control vast terrain. But if you're just doing it for yourself, you're not really a success.

It's not leadership by position that allows people to succeed; it's the capacity to influence the thoughts, the feelings, the emotions, and the actions of other human beings.

In life, never spend more than 10 percent of your time on the problem, and spend at least 90 percent of your time on the solution.

How do you turn the invisible into the visible? The first step is to define your dream precisely; the only limit to what you can achieve is the extent of your ability to define with precision that which you desire.

I'm always loading my brain with new ways of looking at something.

Everything in life and business, you only earn more if you become more valuable. Because if you can do more for people than anybody else does, you can prosper. But you can't do that unless you're constantly educating yourself with the cutting edge. My whole life, even when I had no money, I would invest in education.
