To know oneself, one should assert oneself.

Leap, and the net will appear.

The most effective way to do it, is to do it.

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

It's always too early to quit.

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

If you think you can do it, you can.

Know or listen to those who know.

By failing to prepare, you are preparing to fail.
