Leadership is about making others better as a result of your presence and making sure that impact lasts in your absence.

Let us unite, fight for the independence and freedom of our country.

The only way to deal with the complexity of the world is to simplify it.

"Books are the quietest and most constant of friends; they are the most accessible and wisest of counselors, and the most patient of teachers."

You can't change the past, but you can ruin the present by worrying about the future.

I'm not a businessman, I'm a business, man.
