Easy, I don't want to get in my own way to make myself just more frustrated with that or look bad or humiliate myself etc etc depends on situation as to what the disadvantage would be.

It simply isn't worth it to me to impulsively act on anger when there's a serious disadvantage. This doesn't require much thinking from my part

I'm also in general proud of having satisfying control over my anger, which means I value this control, and that fact helps further control it better too. It requires practice I'm sure. It does require awareness of your state. (I've read but didn't try this: you can use meditation practice specifically for the purpose of install a "circuit breaker" in the way of impulsive emotion, including anger.)

It doesn't mean that I don't express anger, I actually am a temperamental person but it's not like I express it without control. Or I will not express it at all if I don't think it's the right time, in this case I will channel it into an action plan for later, or into achieving a goal that I find more worthwhile than randomly impulsively acting on anger in the moment.

Another part to all this is that if I do decide to act on it, I don't mind having to deal with some consequences. The point is that I make a conscious decision to act on it, it's not a thoughtless impulsive act.

If I do - rarely - lose my head then I don't like that, sure, but I find it's over smaller things, not the big, important things. The important things is where I get really focused.

I am sure it would help me to use humour too like OP does. I would need a LOT of practice there as it is now, lol.
