If you think you can do it, you can.

Either you run the day or the day runs you.

I can, therefore I am.

Know or listen to those who know.

Do not weep do not wax indignant. Understand.

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

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

It's always too early to quit.

If you can dream it, you can do it.
