I can, therefore I am.

If you think you can do it, you can.

Be gentle to all and stern with yourself.

To know oneself, one should assert oneself.

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

Always desire to learn something useful.

If you've got a talent, protect it.

Do not weep do not wax indignant. Understand.

If you can dream it, you can do it.
