Physician, heal thyself.

Physician, heal thyself.
Prov. Do not rebuke someone for a fault or problem you have yourself. (Biblical.) Ellen: You're such a spendthrift. You should go on a strict budget. Fred: But you manage money even worse than I do! Physician, heal thyself. Jane: You look like you're gaining weight. You should probably get more exercise. Alan: Physician, heal thyself. You're getting a little pudgy, too.
