What is the porpouse of life?

This question is very similar to one posed in the Hitchhiker's Guide to the Galaxy, which asked about the answer to life, the universe, and everything, and proposed that it is 42. A more realistic answer would be, your purposes are your own. You are free to adopt any purpose you wish. The universe does not impose a purpose on you. Going back to the Declaration of Independence, we might propose that the normal goal of human beings is the pursuit of happiness. We would all like to be happy. It's a reasonable goal. But you are free to choose another purpose, if you wish.
