Never complain and never explain.
The wise does at once what the fool does at last.
Know or listen to those who know.
Quality is not an act, it is a habit.
Well done is better than well said.
If you think you can do it, you can.
Be gentle to all and stern with yourself.
Be kind whenever possible. It is always possible.
The secret of getting ahead is getting started.
Always desire to learn something useful.
Happy people are ignoramuses and glory is nothing else but success, and to achieve it one only has to be cunning.
