I missed the comment from the pp who said she believes in her own brilliance, but I resonate with it - I do believe I'm better at lots of things than many people, although I do also recognise there are plenty of things where others have more ability as well.
Re your questions, I have a very quick temper, but it falls as fast as it rises, so there might be a brief period of shouting or taking myself elsewhere to cool off, but no, I don't hold grudges. Takes up too much brain space that I'd rather use for something else, so I suppose I could, but I've never seen the point so choose not to, but cognitively rather than emotionally, I guess.
Humour - yes, I do, but people have different senses of humour, so I might not find it funny just because you do, and if I don't I probably won't laugh along in a social cohesion kind of way, but I do find lots of things funny. Including (but not only) very clever humour and black humour that others may find a bit too dark...
Which also made me think - I think I have a different reaction to grief/bereavement than others. It's quite easy to just feel "well, they're dead, there's nothing I can do about it, so.... Next...", which I feel is quite incomprehensible to many. And I'm never upset about anything in the news, for example. It's a thing happening out there, which has very little relevance to me, so the reaction is no more than "oh, that's interesting", or "people are arseholes" or similar.
Re the "do you have to stop yourself acting in an unlawful way?" - it depends what you mean. I don't commit, e.g. fraud or theft or violence, because they're at odds with my morals and ethics, and it's much more that which governs my actions than because they're illegal.
Small things - I work on my own operating model for the universe. So largely, I don't follow rules because they're there, but if I agree with the reasons for them, then I'll be acting in accordance with them anyway.
But I feel zero need to follow rules because there's a rule there, if you see what I mean. Sometimes (rarely), I'll follow a rule I don't believe in because there might be negative consequences to not doing so, but mostly, if I don't agree with it I just ignore it. And in general this also brings close to zero negative consequences, and often has benefits. I don't tend to advertise it though, because people have opinions about it, and frankly I don't agree, won't agree, and find the conversation tedious!
I suspect it may be linked to the "I know better than others" aspects of thinking. Many rules are (IMHO) put in place to keep the lowest common denominator in line. So if you're smart enough to think round them, then I don't see that there's any obligation to comply with rules I consider stupid. But I would support anyone in doing that, it's not particularly that I think I'm special in that regard.
