I guess when you detach yourself from issues that you thought were humongous and put yourself in perspective, like when you see that even the solar system can be just a dot and insignificant in the universe, it kind of gives you a spiritual edge, and so the only thing that becomes important in life is feeling good about yourself. So whether you're searching for things that you're passionate about on the ground floor or 100th of the evolution ladder, your soul will only be stimulated if your eventual goal is happiness, not fame and riches.
