Be gentle to all and stern with yourself.
By failing to prepare, you are preparing to fail.
Only the educated are free.
Well done is better than well said.
Expect problems and eat them for breakfast.
The dog that trots about finds a bone.
Who seeks shall find.
To know oneself, one should assert oneself.
Problems are not stop signs, they are guidelines.
Be kind whenever possible. It is always possible.
Well-timed silence is the most commanding expression.
