I can, therefore I am.

The secret of getting ahead is getting started.

If you think you can do it, you can.

Only the educated are free.

Leap, and the net will appear.

Go for it now. The future is promised to no one.

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

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

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