To know oneself, one should assert oneself.
Be gentle to all and stern with yourself.
If you've got a talent, protect it.
Who seeks shall find.
It's always too early to quit.
Begin to be now what you will be hereafter.
I can, therefore I am.
The dog that trots about finds a bone.
To be a good loser is to learn how to win.
Be thine own palace, or the world's thy jail.
The odds are always against you no matter what your previous history is. You have to overcome the tendency to relax.
