I can, therefore I am.

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

The secret of getting ahead is getting started.

The dog that trots about finds a bone.

If you think you can do it, you can.

Know or listen to those who know.

Begin to be now what you will be hereafter.

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

What you do today can improve all your tomorrows.
