For me, having a clear purpose in my life has been essential. But it was something I had to think long and hard about before I understood it. and ultimately figured out the purpose of my life.
My purpose grew out of my religious faith, but faith isn’t the only thing that gives people direction. For example, one of my former students decided that his purpose was to bring honesty and economic prosperity to his country and to raise children who were as capably committed to this cause, and to each other, as he was. His purpose is focused on family and others—as mine is.
The choice and successful pursuit of a profession is but one tool for achieving your purpose. But without a purpose, life can become hollow.
