I couldn't help thinking some more about what you wrote. The things I want to do, like reading a specific book, only make sense if I am alive. If I die, my desire to read the book disappears. I would not say I want to live in order to read this book. I would say I want to read this book if I am alive. But I agree with you that people can sometimes have a sense of purpose, of things that should be accomplished in their life. I remember I had this a long time ago. I'm still working on what I then thought I should do. In the meantime I have lost the feeling I must absolutely live so that my work can be accomplished. But the fact this feeling exists does make me think there is something wrong with my argument. You are right it is rational to pursue things you like or avoid things you dislike and following your instincts. At the same time your different instincts are often in contradiction, and you rationally chose which one to repress. So the fact you have an instinct doesn't mean you should never repress it, and having an instinct of survival doesn't necessarily mean it would be good to live forever.
