How to parent yourself out of your son

Basically the title. I was a little hoodlum despite having a great childhood, my dad was the same and I can already see the signs in my 2 year old.

I just don't want him going down the same path of alcohol, drugs, loose women, fast cars and fighting like my dad and I both went through. We ended up being normal guys with great careers but I almost died dozens of times and cannot figure out how to make sure my boy keeps it between the lines without also turning him into a Ned Flanders.
