I shall allow no man to belittle my soul by making me hate him.The greatest remedy for anger is delay.How much more grievous are the consequences of anger than the causes of it.

Anger gives them control of you

When someone wrongs us, there's an almost magnetic pull to match their energy with our own anger—to prove we're not weak, that we won't be walked over. But Seneca spotted something crucial: by hating them, we're actually letting them win. We're handing them control of our inner life. The real strength isn't in the intensity of our response; it's in refusing to let someone else's actions shrink who we are.

What makes this advice oddly practical is the "delay" part. We don't need to pretend anger doesn't happen or that we're enlightened enough to skip it. We just need to notice that our first impulse to respond is almost never our best one. Wait an hour, a day, a conversation with a friend. The anger usually softens. The clarity usually arrives. And suddenly the grudge we were prepared to carry feels heavier than the original slight ever was.

The sneaky insight here is that we've probably all experienced this backwards—we've held onto anger so long that we can barely remember what started it, but we remember exactly how much it cost us. Seneca's saying: stop paying interest on old debts. Your peace of mind is worth more than being right in the moment.
