When John Lennon told us we all want to change the world, he was right. We all want to make our mark in some way. Each one of us wants our existence to count for something meaningful. Of course, as Frank Capra pointed out in his 1946 fi lm It’s a Wonderful Life, each one of us does change the world just by being in it. In that movie, the James Stewart character (George Bailey), wishing he had never been born, is suicidal until Clarence (an angel) shows him how the community would have fared had he never existed. Just like George Bailey, each of us, just by being born, has altered the future.
