Be gentle to all and stern with yourself.

I can, therefore I am.

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

Problems are not stop signs, they are guidelines.

By failing to prepare, you are preparing to fail.

Never complain and never explain.

Be kind whenever possible. It is always possible.

Do not weep do not wax indignant. Understand.

Quality is not an act, it is a habit.
