Get hyped, by virtue of not being a baby fresh out of high school you are now one of the cool students! I have a few family members that are teachers and they say that older students are usually the teachers’ favorites because they are so motivated. I try to use my position as an old dude to show the youngins it’s okay to ask questions and not know things, and to get excited about stuff. But I’ve also met a lot more people my age and older than I thought I would!
