It's always too early to quit.

To know oneself, one should assert oneself.

Do not weep do not wax indignant. Understand.

If you think you can do it, you can.

The dog that trots about finds a bone.

Leap, and the net will appear.

Without hard work, nothing grows but weeds.

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

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