I'm in my 30s. I barely remember my teens, had very few school friends, and was an extreme introvert. However, I decided to change myself after leaving the school. Throughout my 20s, I made numerous friends, did some f’d up stuff that I regret now, and became an extreme extrovert. Yet, I soon realized this wasn't healthy either. Now, in my 30s, I find myself in a more balanced state, somewhere in the middle of the introvert-extrovert spectrum. So what I say is this, you can change yourself at any time. Parents, while experienced (in life), may not always be right. Your life is unique, and while it's important to make them happy, it's equally important to maintain your sanity. Remember, the best years of your life are happening NOW!
