Quality is not an act, it is a habit.
Be kind whenever possible. It is always possible.
Be thine own palace, or the world's thy jail.
Never complain and never explain.
The secret of getting ahead is getting started.
It's always too early to quit.
If you've got a talent, protect it.
Always desire to learn something useful.
Well done is better than well said.
You never know what motivates you.
The art of leadership... consists in consolidating the attention of the people against a single adversary and taking care that nothing will split up that attention.
When a man assumes leadership, he forfeits the right to mercy.
