I have made good and bad decisions, probably in equal measure! I tend not to dwell on either and live in the here and now. One decision has, however, always interested me as to what my life might have been. I passed civil service exams etc when I was 17 and was invited to work in London in the DSS. I took cold feet and turned it down and went to university instead. I don't regret that decision but I've occasionally wondered what my life could have been.
