"Shoulda, coulda, and woulda won't get it done. In attacking adversity, only a positive attitude, alertness, and regrouping to basics can launch a comeback."

Cling tooth and nail to the following rule: Not to give in to adversity, never to trust prosperity, and always to take full note of fortune's habit of behaving just as she pleases, treating her as if she were actually going to do everything it is in her power to do. Whatever you have been expecting for some time comes as less of a shock.

— Seneca the Younger
