They are blaming bad luck for their shitty personality.

I wish I was the kind of guy who liked being social and meeting new people, but I’m not. I can force myself to do it, but I can’t force myself to do it much (and I think people can tell that I would rather be going to the dentist). I didn’t choose to be like this, and I didn’t choose whatever inborn characteristics and childhood experiences made me end up like this. If there’s a way to choose not to be like this, I haven’t found it. I do think I got unlucky.

I’m not trying to complain about my fate here. I got lucky in a lot of other ways. I’m just saying that it isn’t fair to tell people that they would be happier if only they were someone else.
