There is one important lesson life has taught me so far, which is that life is not a rehearsal you only get one shot at life. Personally that is the best way to put my explanation. You can watch life going by particularly when you are young. When it seems to be endless, and realize that it has passed you by before you know it. Teaching us , we try to see people as they see themselves, the only way to understand them. To appreciate the distinctions between one shade of grey and the other. To believe that if you like people, it is probably that they will like you. To trust people partly because it is too much bother to go around full of distrust and to accept that being let down is among the normal everyday life and can only harm yourself by bitterness. To accept a partners laziness that no doubt inherited, since he never meant to overcome it - so I developed the attitude - why worry! Finally when ever possible, try to rejoice rather than moan.
At the age we are now, I have discovered that one of the things when one is young, you can live a life of infinite possibilities, you can imagine yourself as many different things in life. You can continue to do that until one day you wake up and say "Oh my god, I am a Doctor, this is my life, this the one I have chosen." I am not going to be a round the world sailor, racing car driver, I am not going to be a sheep farmer, the things you fantasize about occasionally. I am not going to spend my life in Antarctica as a scientist, all the things that "Could have been," even ten years ago you realize "this is it," This the one life I have had and how short it really was.
We learned that you can lose everything in life but what you should not lose is your dignity as a human being. Otherwise you have lost the battle of life. Creating a life in the simplest of moments is nothing more wonderful. This leads to say "The world is perfect as I found out in my time on earth and god knows what he is doing even though we do not."
