What would you tell your 16 year old self?

I'd tell her that it's very important to go to a good university abroad and that school isn't everything, it's not needed to give every subject 100% and get the best grade possible. It's more important to build network in the real world, meet people, get work experience, snatch chances to travel while being a student and using the advantages which that status offers. I'd also tell her that she won't like most of it, she'll feel a lot of anxiety but that there are methods to alleviate it and tell her what to do to manage anxiety better.
