Never complain and never explain.
If you're going through hell, keep going.
Be thine own palace, or the world's thy jail.
Do not weep do not wax indignant. Understand.
By failing to prepare, you are preparing to fail.
Be kind whenever possible. It is always possible.
Problems are not stop signs, they are guidelines.
To know oneself, one should assert oneself.
The secret of getting ahead is getting started.
Things do not happen. Things are made to happen.
A leader must have the courage to act against an expert's advice.
