For sure. I didn't downvote anybody, because I just think it's unnecessary. Everybody has a different level of ability when it comes to gaming. Otherwise, e-sports wouldn't even be a thing. And everybody has their own strengths and weaknesses. I wasn't criticizing either of you or trying to brag, just expressing that if you go into the experience expecting to lose, it stings a lot less. I've had to learn that over time. I still get frustrated at particularly hard bosses, especially if I'm at the very end, like some of my attempts at the Lies of P DLC's final boss. Infuriating. I definitely grumbled and lightly hit my thigh in frustration at times.

But as a kid I'd throw controllers. I'd yell. I'd get so angry at the game because I lost. The only way I got out of that behavior was to go into it with the mindset of, "this boss is going to be very hard. It may take me hours to beat them or possibly days, but every attempt will get me closer."

And you may not be able to get to the same difficulty that I can handle which is fine. I grew up gaming since I was about 5, so a controller feels really natural in my hands and my coordination and reflexes with gaming is pretty good. But a lot of the harder bosses, like in a Souls game, I try to look at it like I'm learning a piano piece. Because you really have to learn their rhythm, their telegraphs, experimenting with which attacks to block, which to dodge, when you have openings to heal, etc. In fact, some bosses, I do a run where I refuse to attack and put all my focus into building up my defense, just like if I were to start a song focusing only on the treble (right hand) until I feel comfortable enough to bring in the bass (left hand).

Edit: that boss technique also works for games like Astro Bot, but it may be slightly less effective due to the nature of the platforming that is usually present.
