The secret of getting ahead is getting started.
To know oneself, one should assert oneself.
Know or listen to those who know.
It's always too early to quit.
Who seeks shall find.
The dog that trots about finds a bone.
Be gentle to all and stern with yourself.
Things do not happen. Things are made to happen.
Expect problems and eat them for breakfast.
After a storm comes a calm.
The sad truth is that excellence makes people nervous.
