To know oneself, one should assert oneself.
Well done is better than well said.
Be thine own palace, or the world's thy jail.
Know or listen to those who know.
By failing to prepare, you are preparing to fail.
It's always too early to quit.
You never know what motivates you.
The dog that trots about finds a bone.
The secret of getting ahead is getting started.
The most effective way to do it, is to do it.
I've learned to have a sense of humor about myself. Lord knows everyone else does!
