You have control over your reaction to things. And I think this is a key component of Stoicism, especially in the modern working world.
If you are acting (and reacting) true to yourself, then it is other's reactions to your actions that are failing. This goes a long way to reducing the amount of stress felt.
Thanks for the insights.
I‘ve had my fair share of yelling at my kids, and regretting it afterwards. Or writing an inflammatory email response. Obviously, I don’t have full control over my reaction, even though I think I‘m a rather careful person. I do have a strong influence, that’s for sure.
I‘ve stopped beating myself up for knee-jerking something. The unconscious has so much control over what surfaces next. I think it was an article here on HN recently that claimed that decisions are formed up to 12 seconds before they become conscious.
