To lead a life that goes beyond pettiness and prejudice and always wanting to make sure that everything turns out on our terms, to lead a more passionate, full, and delightful life than that, we must realize that we can endure a lot of pain and pleasure for the sake of finding out who we are and what this world is, how we tick and how our world ticks, how the whole thing just is.
