I can, therefore I am.

Do not weep do not wax indignant. Understand.

Know or listen to those who know.

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

If you think you can do it, you can.

If you're going through hell, keep going.

By failing to prepare, you are preparing to fail.

What you do today can improve all your tomorrows.

Quality is not an act, it is a habit.
