Be gentle to all and stern with yourself.

If you think you can do it, you can.

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

It's always too early to quit.

I can, therefore I am.

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

If you can dream it, you can do it.

What you do today can improve all your tomorrows.

The secret of getting ahead is getting started.
