brains give me the most gratification. i wish i had more. beauty would be important if i wanted to be social, but mostly whatever you get is whatever you get. money can be very useful, but you won't get as much out of it without the brains to do so. it can make you feel confident, which is ok, but again it won't actually give you what it makes you feel confident about. for that you need not only brains, but actual abilities, skills, even a bit of luck now and then.
Beauty, because you can always increase your knowledge, study, learn. I think deep down, everyone wants to be beautiful. I read a study that showed beautiful people on average earn more money than less attractive ones. An attractive male though, there aren't a lot of really good looking men, and the ones who are attractive command a lot of adoration from women, and respect from other men, who on a subconscious level, admire and look up to his superiority as a man. I mean we're still animals, we can't escape this stuff.
