"I must not fear. Fear is the mind-killer. Fear is the little-death that brings total obliteration. I will face my fear. I will permit it to pass over me and through me. And when it has gone past I will turn the inner eye to see its path. Where the fear has gone there will be nothing. Only I will remain." -- Frank Herbert
Being deemed incapable in certain contexts,
Being emotional with people,
Socialization - to some extent,
Really dirty things like toilet water,
Hmmmmm... That's all I can think of right now.
More or less the same, only not the heights & not the dirty things; I curiously have no "physical" fears at all(I'm always the one who brings spiders outside because I don't want that someone hurts them^^), but quite a many social ones. Though, as a kid, I had some "physical ones": I were afraid of sleeping in the dark and, to some extent, heights(but that didn't stopped me from climbing up every tree I saw, so it couldn't be that strong). The most irritating fear of me is that everything other people say or show to me is faked, just to "not hurt my feelings", or to manipulate me etc. (yeah I know I'm paranoid) To be honest, it's a really stupid fear.^^
They say I only think in form of crunching numbers.....
