Life shrinks or expands in proportion to one’s courage.

Love makes your soul crawl out from its hiding place.

Pain nourishes courage. You can't be brave if you've only had wonderful things happen to you.

A person without imagination is like a teabag without hot water.

Not failure, but low aim, is the crime. In great attempts it is glorious even to fail.

If you are distressed by anything external, the pain is not due to the thing itself, but to your estimate of it.

Let frustration fuel inspiration.

I believe that the privilege of a lifetime is being who you are.

The world belongs to the enthusiast who keeps cool.

You don't meet the people you love, you recognize them.

My life is full of mistakes. They’re like pebbles that make a good road.

That's the very reason they put rubbers on the end of pencils... because people make mistakes.
