I can, therefore I am.

To know oneself, one should assert oneself.

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

Never complain and never explain.

If you've got a talent, protect it.

Problems are not stop signs, they are guidelines.

Do not weep do not wax indignant. Understand.

Well done is better than well said.

By failing to prepare, you are preparing to fail.
