Just as we develop our physical muscles through overcoming opposition – such as lifting weights – we develop our character muscles by overcoming challenges and adversity.

We want Facebook to be one of the best places people can go to learn how to build stuff. If you want to build a company, nothing better than jumping in and trying to build one. But Facebook is also great for entrepreneurs/hackers. If people want to come for a few years and move on and build something great, that’s something we’re proud of.

Any hand that I’ve shaken, any person that I met when I was Joe Blow, now that I’m this guy Kevin Hart, has come back. That’s why I treat everybody with respect. I’m always a nice pleasant guy to meet because when they come back to you, they remember.

The finest steel has to go through the hottest fire.

What can I say? I’m a talker.

Being president is like being a jackass in a hailstorm. There’s nothing to do but to stand there and take it.

I’ve made money, and I’ve been ripped off. I’ve had creative freedom, and I’ve been pressured to make hits. I have dealt with diva behavior from crazy musicians, and I have seen genius records by wonderful artists get completely ignored. I love music. I always will.

You’ll never find a better sparring partner than adversity.

The worst part of success is, to me, adapting to it. It’s scary.

If a whole bunch of people want to make your life a living hell, they’re gonna do it.

When I started my last business, I didn’t receive a paycheck for 13 months. The average person can’t handle that pressure.

It’s kind of like a challenge to myself to be able to hear somebody else’s hook and kind of interpret the words. Because my own hooks, I already know what I mean when I write them.

The ultimate measure of a man is not where he stands in moments of comfort and convenience, but where he stands at times of challenge and controversy.

I really miss being able to blend in with people.

The problem with EMMA is that it is cost prohibitive for the small investors who were supposed to benefit from the new transparency.

I wish every American had an opportunity to sit down, to go to a base, to meet with families, to meet with service members, to sit down with our veterans – because we would think differently about our challenges as individuals.

Of course, it does depend on the people, but sometimes I’m invited places to kind of brighten up a dinner table like a musician who’ll play the piano after dinner, and I know you’re not really invited for yourself. You’re just an ornament.

Let’s face it. Umpiring is not an easy or happy way to make a living. In the abuse they suffer, and the pay they get for it, you see an imbalance that can only be explained by their need to stay close to a game they can’t resist.

Only when the tide goes out do you discover who’s been swimming naked.

Even the securest financial plan and the finest health coverage aren’t enough to hold us steady when the challenges come… We need something more, something deeper and unshakeable, something that will see us through life’s hard times.

Life isn’t meant to be easy. It’s hard to take being on the top – or on the bottom. I guess I’m something of a fatalist. You have to have a sense of history, I think, to survive some of these things… Life is one crisis after another.

Sucking up to the biggies won’t get us anywhere.

After a hard day of basic training, you could eat a rattlesnake.

You can make more friends in two months by becoming interested in other people than you can in two years by trying to get other people interested in you.

I think Clinton, after getting into office and into Washington, was shocked at being bludgeoned. So he spent time trying to be all things to all people – one way guaranteed not to be successful or respected in a lion’s den. You can’t just play around with all those big cats – you’ve got to take somebody on.

I didn’t want to play it boring and safe. I also didn’t want to innovate too much. Second albums, man, they’re even scarier than first ones.

Difficulties are things that show a person what they are.

Life is thickly sown with thorns, and I know no other remedy than to pass quickly through them. The longer we dwell on our misfortunes, the greater is their power to harm us.

In truth, I did enjoy the benefits of a Harvard connection.

Being flooded with information doesn’t mean we have the right information or that we’re in touch with the right people.

I know that I’m not the easiest person to live with. The challenge I put on myself is so great that the person I live with feels himself challenged. I bring a lot to bear, and I don’t know how not to.
