“If you want to be president, you have to know why the heck you are running,” said former president Bill Clinton. Mr. Clinton was discussing his time in office and what it takes to become president at the George W. Bush Presidential Center.

I think you have to begin with the end in mind.

Yeah, you have to win the election, but why in the Heck are you running?

If you want to be president, realize it is about the people, not about you.

And when it is over, and that’s what a lot of these people who get real arrogant in office, they forget. Time passes. And it passes more quickly than you expect.

You want to be able to say: People are better off when I quit, kids were having a better future, things were coming together.

You don’t want to say: God, look at all the people I beat. The people I worked over.

I think the most important thing is to be humble, to listen, to realize everyone has a story.
