Hi. I worry far too much about life. Mostly about stupid stuff like "I'll never go down in history". That's the main one actually. It's getting to the point that I can't really concentrate on anything I enjoy. I sit and read up on mathematicians like Terence Tao, and ask myself constantly, "why am I not doing that?...I'm behind! He had his degree by 17, I'll be 21 by the time I get mine...that's four years". Truth is, as you probably know, I have nowhere near his passion or (probably) intelligence, and that he actually cares about maths beyond it just being a means to prove intelligence: I now spend most of my time learning maths and preparing for maths competitions in the hope I can prove my cleverness. I often do well in them, and people seem to respect me, but it brings me no happiness, I see it as a duty to get this respect. I really really want to relax, do the things I love and enjoy life while I'm young, but I just can't until I can say for sure: "It's all futile. I should do what makes me feel happy at the time." That's where your book recommendations come in. I want books which lean towards saying that it really is futile trying to win respect, so books on the following: -will the human race die out, and if so, how? -will the species that replaces us keep record of our achievements? Will it be more intelligent than us, so regard them all as crap? -Will planet earth eventually be destroyed? What about the universe? -Do others actually care about the achievement of somebody else? -Could I live again if the exact chemical makeup of my brain at this precise moment (so including all memories stored in chemical form etc) happens again, and if so, is it likely?
