At a recent training, I learned a simple yet powerful exercise for thinking about our power to choose. Draw a vertical squiggly line on a piece of paper. At the bottom write the year you were born. At the top, write the age you’d like to live to be. Place a dash on the line that represents your age today. From that dash to the bottom is your past. From that dash to the top is your future. As C.S. Lewis reminds us, “you can start where you are and change the ending.” What will you choose for your future?
