I used to be a hothead. Whenever anyone said anything, I’d think of a way to disagree. I’d push back hard if something didn’t fit my world-view.
It’s like I had to be first with an opinion — as if being first meant something. But what it really meant was that I wasn’t thinking hard enough about the problem. The faster you react, the less you think. Not always, but often.
It’s easy to talk about knee jerk reactions as if they are things that only other people have. You have them too. If your neighbor isn’t immune, neither are you.
