That is to develop your own philosophy. I always thought philosophy was one of the most useless subjects in the world. It's extremely important in how you perceive the world and your place in the world and what happens in the world. Is it luck? Is it fate? Is it coincidence? Is there a pattern to history? Do things repeat themselves? What in human nature is inherited versus self-determined? All of those things are so important in how you deal with the changes that happen in life -- how you deal with your successes, your failures, with love, with loss.
