Joel Ien, Marci Ien's father and a celebrated teacher and professor, always started the school year by putting two numbers, say 1905 and 1942, separated by a dash, on the chalkboard. Then he would ask his students, "What do you think that dash means?" And his answer was this: The dash is your lifetime. All the years that come between the two dates are compressed into that dash. What will you do during those years? How will you find meaning and purpose in life? The paradoxical secret to finding meaning is not to look for it.
