I'm worried about my extra curriculars, to be honest.
By senior year, it'll be something like this (hopefully; the sports may not work if I'm not good enough, but I'm always doing my best to improve)
Varsity Volleyball, Varsity Basketball, Varsity Lacrosse, Classical and Acoustic Guitar for 6 years, Piano for 9 years, Model Congress (leadership), School Newspaper (higher ranks), Choir or Radio Station [I have not yet decided] for three years, Acrylic and Oil Painting, Teaching Children at Church About God, Personal Research Projects, and possibly Acting School if we can afford it by then.
I'm not amazing enough at any one thing to win major awards and whatnot. But I am relatively good at most things, and I tend to like everything, which is why I have so many extracurriculars. I would not be able to easily write about just one of my ECs in a deep way, but I could certainly write a great essay on how all of them have affected me so much.
Is that a problem?

I don't want them to think I'm trying too hard to impress them. I really am not. All of these things represent my interests--sports, music, art, debate, extra learning, communication mediums and singing, religion, helping children, drama...but I'm afraid it all looks like a big slop of "I'm going to enroll myself in everything so that I can get into college!!!" Especially since I'm not the best at any one thing.
Do you think that Adcoms would see it that way?
(I am an incoming freshman worrying far in advance, yes...)
