Dear...19 year old self

I was watching a video by Tarenguy or Taren916 on Youtube, the other day the series was called "A Women's Perspective [dating]. One of the questions it was asked what would you tell your younger self well I started to thinking really hard and boy are there so many things I'd like to say to my younger self. I mean I am still young I guess (25) and I still make mistakes in dating but I have way more wisdom than I was say when I was 18 or 19.
