My current self would be so tough on my younger self if I was the personal trainer for my young self.
My young self would be like. "I don't want to run anymore. I'm tired."
My current self would be like, "Oh yeah. You don't have the eye of the tiger. You need to do more."
My young self would respond, "That was just a movie. What's with all this running? I'm not going into the Olympics. Why are you so tough? Am I going to become tough?"
My current self, <looks off into the distance> "If you work hard now, it will pay off in the future. You think you're fast, but you aren't. You aren't fast enough."
