You will be surprised how many people in your school, were you work, your church, or whatever, plays guitar and there is always someone better and someone not as good as you. I started out playing just bluegrass and the old mountain folk music. Now I love the old & new country, jazz, blues, folk, old rock 'n roll, bluegrass, and americana. I love going to the festivals and just hanging out in the parking lot playing with people I don't know. I learned a lot and really enjoy it!
I went from the Carter Family to Tracy Chapman because of what I learned.
Your interest in playing with grow with the more you learn and can accomplish and vise versa. BrokenJera is right. You need to try different styles. You will be amazed at what they have to offer. But you need to jam as well.
Good luck!
