If you believe you can change the world, which I hope you do, do what you believe is right and expect resistance and expect attackers.

If you let pride stop you, you will hate life. 

Just because they say it can’t be done doesn’t make it so.

If you want to have more, do more, and be more, it all begins with the voice that no one else hears.

You can fail at plenty as long as you get a few important things right.

Most information is time-consuming, negative, irrelevant to your goals, and outside of your influence. 

Don’t dismiss people, don’t be a dick, and don’t rush. Play the long game.

Go to the gym and move for at least 30 minutes. For me, this is 80% of the battle.

Sometimes, it just takes one conversation with one rational person to stop a horrible irrational decision.

I know nothing. I am a beginner. But I ask a lot of questions.

Think big and don’t listen to people who tell you it can’t be done. Life’s too short to think small.

"The difference between successful people and really successful people is that really successful people say no to almost everything."

"It's better to hang out with people better than you. Pick out associates whose behavior is better than yours and you'll drift in that direction."

"I won't say if my candidate doesn't win, and probably half the time they haven't, I'm going to take my ball and go home"

"I insist on a lot of time being spent, almost every day, to just sit and think. That is very uncommon in American business.

"I just sit in my office and read all day"

The first rule is not to lose. The second rule is not to forget the first rule.

The investor of today does not profit from yesterday's growth.

In the business world, the rearview mirror is always clearer than the windshield.

Beware of geeks bearing formulas.

Rule No.1: Never lose money. Rule No.2: Never forget rule No.1.

The smarter the journalists are, the better off society is. For to a degree, people read the press to inform themselves - and the better the teacher, the better the student body.

I am quite serious when I say that I do not believe there are, on the whole earth besides, so many intensified bores as in these United States. No man can form an adequate idea of the real meaning of the word, without coming here.

The business schools reward difficult complex behavior more than simple behavior, but simple behavior is more effective.
