It's always too early to quit.

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

I can, therefore I am.

What you do today can improve all your tomorrows.

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

Leap, and the net will appear.

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

Know or listen to those who know.

Things do not happen. Things are made to happen.
