Living at risk is jumping off the cliff and building your wings on the way down.

Yesterday I was clever, so I wanted to change the world. Today I am wise, so I am changing myself.

The only way to escape the corruptible effect of praise is to go on working.

It is better to rust out than wear out.

Times and conditions change so rapidly that we must keep our aim constantly focused on the future.

If we could sell our experiences for what they cost us, we'd all be millionaires.

We reap what we sow. We are the makers of our own fate. None else has the blame, none has the praise.
