I just heard this poem on an episode of Without a Trace. I loved it and thought you would too.
It is written by Dawna Markova , author of the book I will not die an unlived life: Reclaiming Purpose and Passion.
Book Description from Amazon: Twenty years ago, faced with a life-threatening illness, Dawna Markova began a journey of rediscovery. This book follows her path to finding deeper meaning in life. As she points out, people can continue to feel powerless and live habitual lives – or they can make the choice to follow their passion.
