How can I be popular in High School?

I know how this sounds but please read all the details. I came from an elementary school where I was considered “cool” and it was nice. I’m pretty shy so it took me a while to get “there” and I think I’m pretty mature for my age. I’m not going to lie but being popular at school is the best. Great friends, good grades, it was awesome.

I felt a bit different from others. I wanted to show that you didn’t have to do drugs or be a douche bag to be popular and I was able to do this in elementary school. I felt like a redefined “popular.” I wanted to be a sort of role model maybe. I want to do this in high school too.

Unfortunately this year I had to go to a new high school where I didn’t know anybody. I am pretty shy so it’s kind of hard for me to meet new people easily. I don’t know what to do. This question may sound silly but I feel like I can really do something. I want to get in with the “cool” kids again. Does anyone know what I can do?

Thank you for taking the time to read this question.
