The problem often not discovered until late in life is when you look for things like love, meaning, motivation, it implies they're sitting behind a tree or under a rock. Successful people recognize that in life they create their own love, they manufacture their own meaning, they generate their own motivation. I'm driven by two main philosophies: know more today about the world than I knew yesterday, and along the way lessen the suffering of others. You'd be surprised how far that gets you.
