Diogenes to Crates.

Don't forget that I gave you your life-long poverty. Try not to lose it, and neither let anyone else steal it from you, since it's likely that the Thebans—deeming you unhappy—will accost you. But consider your ragged cloak a lion's skin, your staff a club, and your wallet the land and sea which feed you: for thus would the spirit of Heracles, mightier than every turn of fortune, stir in you.

...but if you happen to have any lupines or dried figs left, please send them to me.

(Cynic Epistles, Diogenes XXVI, as adapted by yours truly.)
