Courage is grace under pressure.

The separation of church and state is a source of strength, but the conscience of our nation does not call for separation between men of state and faith in the Supreme Being.

When I was a young man, Dirac was my hero. He made a breakthrough, a new method of doing physics. He had the courage to simply guess at the form of an equation, the equation we now call the Dirac equation, and to try to interpret it afterwards.

Don’t let your ego get too close to your position, so that if your position gets shot down, your ego doesn’t go with it.

What I admire most about Hillary is that she never buckles under pressure. She never takes the easy way out. And Hillary Clinton has never quit on anything in her life.

It was high counsel that I once heard given to a young person, ‚always do what you are afraid to do.‘

If it’s stress of things that we cannot control, what you have to do is you mitigate that stress as much as possible. You’ve planned, you’ve trained, you’ve done everything you can in your power to mitigate the stress that’s facing you. And then after that, there’s nothing you can do. So, you have to let that one go.

That man is not truly brave who is afraid either to seem or to be, when it suits him, a coward.

Only if you have been in the deepest valley, can you ever know how magnificent it is to be on the highest mountain.

It was really hard for them to intimidate me. They felt I was intimidating. One of the growers had a name for me: I think it was ‚dragon lady‘ or something like it.

The future doesn’t belong to the fainthearted; it belongs to the brave.

Everything negative – pressure, challenges – is all an opportunity for me to rise.

The finest steel has to go through the hottest fire.

Courage – you develop courage by doing small things like just as if you wouldn’t want to pick up a 100-pound weight without preparing yourself.

Nothing happens to any man that he is not formed by nature to bear.

A leader does not deserve the name unless he is willing occasionally to stand alone.

Intelligent people should learn from their experiences. With people on the street, the bad experience has beaten them.

I can’t jump the highest. I’m obviously not the biggest, not the strongest.

Losing is tough.

Eight years ago, you may remember Hillary and I were rivals for the Democratic nomination. We battled for a year and a half. Let me tell you, it was tough, because Hillary was tough. I was worn out. She was doing everything I was doing, but just like Ginger Rogers, it was backwards in heels.

It is unwise to be too sure of one’s own wisdom. It is healthy to be reminded that the strongest might weaken and the wisest might err.

The block of granite which was an obstacle in the pathway of the weak, became a stepping-stone in the pathway of the strong.

It’s a real strength for me that I’ve never minded the training process. It’s something I enjoy. I really like being in the gym or, certainly, on the field.

One likes people much better when they’re battered down by a prodigious siege of misfortune than when they triumph.

Heroes may not be braver than anyone else. They’re just braver five minutes longer.

The truth is: Belonging starts with self-acceptance. Your level of belonging, in fact, can never be greater than your level of self-acceptance, because believing that you’re enough is what gives you the courage to be authentic, vulnerable and imperfect.

Even the knowledge of my own fallibility cannot keep me from making mistakes. Only when I fall do I get up again.

If patience is worth anything, it must endure to the end of time. And a living faith will last in the midst of the blackest storm.

Power over others is weakness disguised as strength.

I worked out early on to give up things I couldn’t do well at all.

And when a woman’s will is as strong as the man’s who wants to govern her, half her strength must be concealment.

Just as courage is the danger of life, so is fear its safeguard.

I always knew from that moment, from the time I found myself at home in that little segregated library in the South, all the way up until I walked up the steps of the New York City library, I always felt, in any town, if I can get to a library, I’ll be OK. It really helped me as a child, and that never left me.

A house divided against itself cannot stand.

In the depth of winter I finally learned that there was in me an invincible summer.

A great part of courage is the courage of having done the thing before.

It is folly for an eminent man to think of escaping censure, and a weakness to be affected with it. All the illustrious persons of antiquity, and indeed of every age in the world, have passed through this fiery persecution.

I don’t ever make moves under pressure.

Cowards die many times before their deaths; the valiant never taste of death but once.

Weak minds sink under prosperity as well as adversity; but strong and deep ones have two high tides.

I continue to care for President Obama and for his family. I think that in many ways they are very courageous people, and I honor that, because I know what it means to live as a black person in a racist America.

All cruelty springs from weakness.

Whether happiness may come or not, one should try and prepare one’s self to do without it.

Without pain, there would be no suffering, without suffering we would never learn from our mistakes. To make it right, pain and suffering is the key to all windows, without it, there is no way of life.

Adopt responsibility for your own well-being, try to put your family together, try to serve your community, try to seek for eternal truth… That’s the sort of thing that can ground you in your life, enough so that you can withstand the difficulty of life.

People want you to fail.
