Do not weep do not wax indignant. Understand.

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

Never complain and never explain.

You never know what motivates you.

What you do today can improve all your tomorrows.

Be gentle to all and stern with yourself.

Expect problems and eat them for breakfast.

Well done is better than well said.

Quality is not an act, it is a habit.
