Take the measure of your luck
in order to act, and in order to commit yourself. This matters more than identifying your predominant humor and understanding your physical makeup. It is foolish for a forty-year- old to ask Hippocrates for health, and even more foolish to ask Seneca for wisdom. It is a great art to govern Fortune, either awaiting her (for she sometimes takes her time) or taking advantage of her (for she sometimes turns good), although you will never completely understand her inconsistent behavior. If she has favored you, proceed with boldness, for she often loves the daring and, like a dazzling woman, the young. If you are unlucky, act not. Withdraw and save yourself from failing twice. If you master her, you have taken a great step forward.
