What I would give to do some large parts of my life all over again from scratch!
Ditto, although I really think that things happen for a reason and have often thought that if I had done things different then I would not have met my wife. I had planned to leave the UK and move to Canada back in 2001 but just as I went out there on a holiday to investigate job opportunities I met my other half, we hit it off and she persuaded me to move to Oz. There are some outcomes I would like to change but I'm not sure that changing things that I have done in the past would bring benefit - some of my biggest cock ups have led to other good things happening.
