Rage unfailingly makes you a pawn in someone else's game. You should always be wary of anyone telling you that you need to be angry.

The Stoics inherited the Cynics attitude that death isn't an evil. If worse comes to worst, you can always just fall on your sword. They used to say that the door is always open. Marcus Cato weaponized this fact to rob Julius Caesar of complete victory: Caesar couldn't demand his submission if he fell on his sword first. They found him and patched him up. But he ripped out the stitches and disemboweled himself with his bare hands.
