How to save a life?

I have been thinking about life. In fact I think about it a lot. What does it mean? What is my purpose? How can I know that I have done well with my fair share of it? These are all questions that only I can answer. No book or religion or person can tell me these things, but even as I write this I know that we as human beings are simply nothing more than the sum of our experiences. The things that we go through in life, the good and the bad determine how we look at life and give us the lessons we take with us on whatever path we tread. I have seen a few things here and there, experienced immeasurable joy and sorrow and like a rope maker I have beaten the strands and wisps that make the bonds of true friendship. I have always thought that my purpose in life was simply to love and to be loved and though life in all its fickleness has conspired to make me believe otherwise I have held fast to these beliefs. Now like some poet long since dead, I stand on the edge of a surf tormented shore and I ask the Gods that be, of small things and those of great consequence, that one day I can save a life. For then I will know that my life has been worth something and I will be absolved of all my indiscretions.
