The Art of Generalizing-III

I really expected the chap to snap at me to go boil my head when I asked him for a simpler way to start on this Art. For a moment, it did look like he wanted to rearrange my face with his fists but, thankfully, the moment passed.
"I thought I was giving you a cheat sheet and now you want a cheat sheet for the cheat sheet!? Well, the simplest way is to change your mindset. When someone finds fault, you seem to think instantly about what is wrong with your work and try to defend it. Instead, you should learn to instantly think, 'What is wrong with this guy that he is finding fault with my work?' THEN, you will find ways, ranging from that chap's own lack of ability to the various generalizing possibilities to counter him effectively."
"You mean...when I am think of my possibly being wrong is when I appear to be unwilling to take criticism? And when I automatically assume that the fault is in the other guy is when I seem to be taking it well? That does not seem right."
"You will never learn. Next thing you will be saying is that the chap who appears the most busy is the guy who does the most work. Just take it from me. You have to have unshakable confidence that you are right...like, you know, when someone opposes your leader, you can call him a Bhakt or Libtard or whatever and go hammer and tongs at him. THEN you have no problems in adopting the art of generalizing, do you? Whatever the specific issue, you..."
"THAT is because my leader is infallible. He can do no wrong. So..."
"Exactly! You have to assume YOU are infallible. Then, you will know what to do automatically. Though, yes, it is easier to assume that your leader can do no wrong. When it comes to you, though, your memory can inconveniently pop up instances of when you made an ass of yourself."
That last was true but this thinking of myself as always right...that I felt optimistic about managing with practice.
"Thanks, dude! I think I can manage this from now."
"What have I done?" he wailed. "You were insufferable even without this. Now..."
And THIS was the guy I thought was sympathetic!
"But...a feeling of infallibility has to be bone-deep. Otherwise, you can never manage it in the heat of the moment. So, maybe, not much damage done after all."
Ye Gods! Was I still going to be no better after all this learning?
