To know oneself, one should assert oneself.

Well done is better than well said.

Always desire to learn something useful.

If you're going through hell, keep going.

What you do today can improve all your tomorrows.

Expect problems and eat them for breakfast.

If you think you can do it, you can.

The wise does at once what the fool does at last.

Quality is not an act, it is a habit.
