I came to understand that happiness and vulnerability are often the same thing.

Uncertainty is where things happen. It is where the opportunities - for success, for happiness, for really living - are waiting.

The effort to try to feel happy is often precisely the thing that makes us miserable.

True security lies in the unrestrained embrace of insecurity - in the recognition that we never really stand on solid ground, and never can.

...It's more important than ever that we find new ways to cultivate curiosity - because our careers, our happiness, and our children's flourishing all depend upon it.

Part of the problem with positive thinking, and many related approaches to happiness, is exactly this desire to reduce big questions to one-size-fits-all self-help tricks or ten point plans.

...no matter how much success you may experience in life, your eventual story - no offence intended - will be one of failure. Your bodily organs will fail, and you'll die.

People have done this before, but not us.

The minute you start talking about what you're going to do if you lose, you have lost.

The 'Always Keep the Faith' tattoo I have on the front represents my desire to protect my beliefs.

If the B2 is invisible, just announce you've built 100 of them and don't build them.

Use of the word; the word itself was not printed.

Why can't I beat up John Cena?

Those who fled will fight another time.
