A lot of girls call me cute but they call my friends hot, is it better to be hot, if so then how do I become hot and not cute.

"Hot" and "cute" are both based on changing ideas and is based on what someone looks like. You could be "hot" or "cute" today because of your Bieber hairstyle and ignored tomorrow because another "look" (such as dreads or bald) is popular. I'd rather be considered "nice" and "fun" and "interesting" and "smart."

Hot is subjective and changes with the times. It's best to be you. Nothing wrong with being called cute.
