I can, therefore I am.

The secret of getting ahead is getting started.

The most effective way to do it, is to do it.

It's always too early to quit.

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

If you think you can do it, you can.

Well done is better than well said.

Problems are not stop signs, they are guidelines.

What you do today can improve all your tomorrows.
