Couple of things Doc, blew the chance to be a footballer, didn't take a job as a sparky on cruise liner, but hey my way of thinking is what will be will be if I had done those things I wouldn't have met my wife so Result to me I think.
I don't think there has been anything major...but hey....it is all part of the learning experiance,right?..I too,probably wouldn't marry again-but I still don't see my 2 as mistakes.
