While this is an after-the-fact statement, I bet each of these celebrities would've stated something siimilar even prior to their success. They had a very clear idea that encompassed and drove their personal philosophy, career goals and family values all in one.
This project statement can serve as a great personal tool for anyone; as a daily reminder of why you wake up in the morning, when in doubt of your ability, and when someone asks you, "what do you do?" Take a little time out to figure out what your goals are and narrow them down into one or two sentences, starting with "My project is to...". It can't hurt and I bet it'll make you think differently about what your life focus is.
