It's hard to say what I regret, because to have regret may also imply you knew of a better option; too often when I start to have regrets I end up dissecting why I feel that way she usually I recognize that I was simply young, ignorant of my potential, and without the role models to help guide me.
We live this life with no instruction manual, so we're building our life by looking at images of other lives. Regrets teach us how to make hard decisions going forward; I'm glad the person the video recognized how to grow from their regrets, because that's all we really can do.
