I have met brilliant minds. They fascinate me. But somehow it is like a D&D game: you can only distribute your 100% total in intelligence, social skills, etc. Put everything into intelligence and you lose all other skills.
I once met this brilliant guy working as a programmer and heavy maths. He had really poor social skills. At the gala dinner you could literally see him mentally compile code, while others were having a laugh. It was so bad that he couldn't really coordinate his body. I mean he could walk, but it looked strange. But yes, he was the brightest mind in the company. He could solve math problems in no time. When he was hired, in the interview they gave him a math problem that nobody could solve, just to see how the candidate would handle it. Well, he did solve it.
I know that I am not dumb and fairly smart. But I have met people that are so much smarter than I. Where I need to read a concept several times and think about it, so that I finally understand it, others get it on the first reading.
It is no problem to not be as smart, as other skills like social skills get you further than smartness alone.
Want to see an example of smartness? I find this video amusing:
Still have not fully understood all the details...
