I can, therefore I am.

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

If you can dream it, you can do it.

The secret of getting ahead is getting started.

If you think you can do it, you can.

To know oneself, one should assert oneself.

Be gentle to all and stern with yourself.

Do not weep do not wax indignant. Understand.

The dog that trots about finds a bone.
