If I could have just....?

We will never be more innocent, easily influenced and vulnerable than when we were teenagers. Some time ago I was surfing through YouTube videos, something I do often for educational and research purposes mostly. I came across a video by a young woman, probably in her twenties who posed a very interesting question. So I'm going to bite a bit from her.

 I'm hoping she doesn't mind, it is a great question!

So I will pose that same question to you....ladies.

If you could advise your teenage self, knowing what you know now, what would you tell your younger self that could change, or alter the course of your life as it is now? And would you want to?
