Expect problems and eat them for breakfast.
To know oneself, one should assert oneself.
It's always too early to quit.
Be kind whenever possible. It is always possible.
After a storm comes a calm.
Only the educated are free.
The secret of getting ahead is getting started.
Quality is not an act, it is a habit.
Either you run the day or the day runs you.
The dog that trots about finds a bone.
