I have a few core Missions that define my life—everything is aligned around them. Missions are life journeys with no specific end. Missions are not goals. Missions are infinite games. The power of Missions is found in the clarity they provide: If an opportunity, person, or action does not positively contribute to one of your Missions, you can say no to it. I have clearly defined a Mission within each of three categories: Professional, Personal, and Health. Clearly defining (and embarking on) your missions is the key to unlocking new clarity, focus, and fulfillment in your life.
