Know or listen to those who know.

If you think you can do it, you can.

I can, therefore I am.

Be thine own palace, or the world's thy jail.

The dog that trots about finds a bone.

Be gentle to all and stern with yourself.

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

Either you run the day or the day runs you.

By failing to prepare, you are preparing to fail.
