It's always too early to quit.

To know oneself, one should assert oneself.

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

If you think you can do it, you can.

Be kind whenever possible. It is always possible.

The dog that trots about finds a bone.

Leap, and the net will appear.

Begin to be now what you will be hereafter.

I can, therefore I am.
