To know oneself, one should assert oneself.
Never complain and never explain.
It's always too early to quit.
Be gentle to all and stern with yourself.
The dog that trots about finds a bone.
The secret of getting ahead is getting started.
Expect problems and eat them for breakfast.
Leap, and the net will appear.
Well done is better than well said.
Always desire to learn something useful.
It is easy to believe in freedom of speech for those with whom we agree.
