What's something that you regret not doing in your teenage years ?

i think we are often a product of our environment in our teenage years and have much less control over our choices when contrasted as an adult.

Most of the choices I rememer taking were on narrow margins given my circumstances. In that idea I am not sure I regret or wish I had or did anything different than what I did. For example

I didn't do well with girls when I was young. But it was because I hit puberty later than my ppers, and was from a lower income household than my classmates and was percieved by proxy as less alluring for both those reasons

I didn't take up smoking because some of my buddies joined a boxing gym and later a martial arts gym and I followed them in blindly making smoking a non-option due to endurance needs.

I could make a longer list but in general I reacted to my environment more than proactively planned in life. It is cool being a grownup in that pro-active planning is an option moreso than as a teenager. It also makes the idea of regret harder to conceptually manage.

I regret not losing my virginity lol
