The amount of drugs and drinking I did in my younger years, including drinking and driving. Thank God I never killed anyone, but I did almost kill myself and my friend by wrecking on a mountainside. Luckily I crashed into the part going up instead of over the side. Sadly, I still continued with my partying ways after that. Also, knowing that even today, with 4 adolescent/teenage children, I would continue the same behavior given the right opportunities.
