Each of us has our own Big Five—cherished dreams whose realization means that our life has been a success, in exactly the sense that we ourselves define. Sometimes it’s hard to identify them, but that doesn’t mean you should stop and give up. You just need to start moving in the direction that seems desirable—just like Jack did when he went to Africa in search of happiness. He had long wanted to see the continent, but he couldn’t even imagine the events and feelings that would overwhelm him on the journey.
