Will i end up like every other guy?

I'm 15. Not so social, but have some friends. I'm very emotional. I dont really go anywhere. I just hang at home. But i'm watching "That 70's show" And they are in their 17's and 18's and they are going to movies and hangin out in the basement and just plain out livin life. I WANT THAT SO BAD. Will things change? Will i be a *** my whole life? I do have a part time job.
