Ambition

Start with a really small market and take over that whole market, and then over time find ways to expand that market in concentric circles.

You took a half-swing on this. Take a full swing.

Be afraid to fail. You should be so afraid of failure that you're willing to do anything to succeed.

There's an infinite number of possibilities for you to create for yourself now, today, with no one to stop you but your own inertia.

You aren't here on earth to just go through the motions. If you love doing something, go after it with every part of your being.

The one way to guarantee you're not going to be successful at something is to give up on it. Really ambitious goals — starting a theater company, running for Congress, opening an art gallery in Prague. These things are hard. But even the hardest goal is not that hard.

Dare to say out loud the thing that you actually want and the hard part is actually over. Because then you'll start to make a plan, and when you have a plan, then you'll start to make that plan real.

Don't be afraid to fail big, to dream big, but remember, dreams without goals are just dreams. And they ultimately fuel disappointment.

We cannot always bend the world into the shapes we want, but we can try. We can make a concerted and real and true effort. Always just try, because you never know.

In bringing the president to me, in having me speak to and question a shaper of history and experience the value he saw in my view, Harvard would make me feel I too could be him. I too had the power to shape history and not just be passively shaped by it.

A persistent curiosity can help us reach ambitious goals, even with great roadblocks in the way.

Work hard, like, every waking hour. That's the thing I would say, particularly if you're starting a company.
