Things do not happen. Things are made to happen.

Know or listen to those who know.

It's always too early to quit.

Be thine own palace, or the world's thy jail.

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

Leap, and the net will appear.

Never complain and never explain.

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

By failing to prepare, you are preparing to fail.
