My optimism wears heavy boots and is loud.

Sovereignty is not given, it is taken.

When I'm good, I'm very good, but when I'm bad, I'm better.

As long as I'm in great shape, nobody beats me, for sure.

Don't wish it were easier, wish you were better.

Out of intense complexities intense simplicities emerge.

Faith is taking the first step even when you can't see the whole staircase.

Listen to many, speak to a few.

Out of your vulnerabilities will come your strength.

Alone we can do so little; together we can do so much.

When I'm inspired, I get excited because I can't wait to see what I'll come up with next.

The people who were trying to make this world worse are not taking the day off. Why should I?

I can never stand still. I must explore and experiment. I am never satisfied with my work. I resent the limitations of my own imagination.

If my life is going to mean anything, I have to live it myself.

Every problem has in it the seeds of its own solution. If you don't have any problems, you don't get any seeds.

Storms make trees take deeper roots.

Laziness is nothing more than the habit of resting before you get tired.

You see things; you say, 'Why?' But I dream things that never were; and I say 'Why not?

I'd rather be an optimist and a fool than a pessimist and right.

I hated every minute of training, but I said, 'Don't quit. Suffer now and live the rest of your life as a champion'.

To succeed in your mission, you must have single-minded devotion to your goal.
