How about never make a major decision in anger?
It's part of our culture in TV and movies where someone gets very upset one day and declares "I quit!" or "I'm leaving you" or "I'm moving and you'll never see me again" or similar. These dramatics play well on the screen but in fact it's a terrible way to make major life decisions.
I'm sure it'd be boring to watch characters who say "let me sleep on this" or "we'll discuss this next week" but I wish more people would actually manage their lives like that.
I think it entirely depends on the context and the person.
A decision made out of nowhere during an intense emotional state can lead to making ridiculous and impulsive, and irresponsible decisions.
On the flip side though, sometimes someone has been repressing a need for so long that it takes being pushed too far for them to snap and finally follow their gut.
I have a history of being incredibly disciplined, so some of the best and wisest decisions I've ever made were in a state of rage where all of the "rationale" of my plans fell away, and I was actually able to hear what my gut had been screaming at me for a very long time.
A lot of high performing people are like that. They're willing to put themselves through hell for the sake of an outcome, and it takes snapping for them to finally do something to protect their well being, because they've been programmed not to care about it.
So yes, acting in anger can be incredibly irresponsible, but it can also be the wisest move possible.
