We often hear that someone has left their troubled past behind; they have "turned the page." Of course, unless they had a brain transplant, that is impossible.
We are our past, from the moment of conception until this very minute. We are the product of our genes and our experiences (physical, intellectual and emotional). We are molded by love and rejection, praise and criticism, joy and sorrow.
Though we may wish we could change the past, we can only accept its rewards and learn to deal with its lessons. The future may offer hope but the past delivers reality.
