I can, therefore I am.

Go for it now. The future is promised to no one.

Leap, and the net will appear.

It's always too early to quit.

The wise does at once what the fool does at last.

Know or listen to those who know.

By failing to prepare, you are preparing to fail.

If you think you can do it, you can.

To be a good loser is to learn how to win.
