Be gentle to all and stern with yourself.

To know oneself, one should assert oneself.

Things do not happen. Things are made to happen.

Either you run the day or the day runs you.

If you're going through hell, keep going.

If you think you can do it, you can.

Never complain and never explain.

If you've got a talent, protect it.

Quality is not an act, it is a habit.
