Why can’t I be more beautiful?

I don’t know if this is just me but every single time I try to look beautiful or Pretty it’s just fails to impress other students. I know I’m not trying to be like those ones who want attention but I just want to be appreciated by my classmates cause most of those who look good get love. But when they only look at the ones who aren’t even looking good at all and only treat them better than me. I mean guess personality over looks but I just feel like the world is better than me and I can’t never be beautiful at all.
