How can a middle-schooler striving to excel get ahead?

I'm asking this question on my mom's account: I am in eighth grade and I really want to get ahead. I am in the highest level of all my cles, I get straight A's and I study hard. I do extra-curricular activites but I want to do something completely ahead and out of the ordinary. Do you know of any clubs I can join? Or cles I can take to get high-school/college credits? I already have an internship. I am very lucky to have supportive friends and family but is there anything ELSE I can do to get ahead? ( I already devote much of my time to charity)
