I’m tired of being the idiot!

I miss teaching my knowledge, because in collage everyone knows everything. I feel like the idiot. I can’t express what I have learned, because everyone already knows what I know. The worst thing is that everyone knows much more than me and all I say means nothing. I want amazed others in my grasp of a subject, but they know everything ten times better than me. How can I teach if no one will listen?
