I have an issue really holding me back and it's that I simply suck at smiling. I get told so very often that I need to smile more. I've tried simply forcing myself to smile but it comes off as pretty in-congruent because of it being forced obviously. It has nothing to do with me being sad, this happens even when I'm really happy, it seems that a neutral expression is my default. I would prefer to just not care what anyone thinks and not try to impress anyone, but I do notice that when I shift to that, the other people I'm hanging out with seem to interpret my facial expressions as being negative, and then it just becomes a negative vibe.

Note: this is not purely an issue with girls, it's the same way with my friends and really everyone else...
