Reason to live?

I always thought that the only 'meaningful' way to live is to actually know everything but I dunno if I'll ever have the time to know everything and my mind and time is always occupied with problems that I always skipped at resolving that I should have used to acquire knowledge. So right now my main aim is to collect riches as much as I could. That's right. Since life is soo short, we must make it a rich one. But I don't think I'll ever be the richest man in the world. Hurmm.. so why do I want to live? Happiness and Joy? I think happiness and joy are not permanent. I never knew a person who was happy all his life. So why do we need to live to feel something that is never permanent? So what is permanent? The soul. So I probably should focus on praying to God. But I need money to eat,drink. So in order to live, I need money. So we do need money even if we want to dedicate all our life for the after-life. At least this is how it is in this day and age. Maybe if I was one of those cavemen I wouldn't need money to eat. I would just kill a rabbit or a deer to eat. So what it is that is my reason to live? Would I die content being just Mr.Everybody? NO!! But maybe I should just be a Mr.Everybody and have the same ambition as everybody. But life would be boring. it is exciting now no matter how messed up it is. Life is exciting when you are in the brink of destruction. I love risks. Life is short so better it be exciting. ^^
