The trouble with wishing you had done something different is that point of view is only available with hindsight. Yes, if I knew what I know now then there are things that perhaps I would have done differently but I am quite happy with the things that I did when younger. Some of those things that were legal then have been made impossible to do nowadays with changes in the law. I belonged to a car club and we ran treasure hunts and rallies,even then we had to limit them to 12 cars, that have now been legislated out of existence. Even car clubs are few and far between now. I did a tailoring apprenticeship because every man aspired to decent suits to wear, look how fashion has gone now, but now the market has shrunk to almost nothing. I changed to engineering in my early 30's and made the most of it while raising a family and buying a house and made a it into a job I enjoyed. I've found that it's not what you regret that makes life good, it's what you are proud of in your life. With that in mind I wouldn't want to change any of it.
