It's always too early to quit.

If you've got a talent, protect it.

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

Well done is better than well said.

To know oneself, one should assert oneself.

Without hard work, nothing grows but weeds.

Do not weep do not wax indignant. Understand.

Know or listen to those who know.

Expect problems and eat them for breakfast.
