Where you are going is more important than where you have been. We all have history. Some good and some not so good. Either way, it is history. We can't change it so there is no use dwelling on it..
We can learn from it if we chose. We have the rest of our lives ahead of us. No matter how short or how long, it is what we do with it and how we live it that counts.
If we focus on the opportunities that lie ahead rather than the past, we will continue to lead happy productive lives.
As the quote says, Look at life through the windshield, not the rear view mirror.
