I belive I have found the meaning of human existance. It is to find a passion that makes progress in a field, put your mind and body into it (Or your soul if あなた would like.) and make as much progress as あなた can. But then あなた can't hoard that progress, there is a stage where あなた need to start to pass it on to future generations. This is why as a kid, people seem to lust for information and absorb it, teenagers only want to do what they want to do, and old people talk about the past. Make sense?
