Choice of college help?

i am in 8th grade and i am really starting to think about my life and my future. i am a strait A student and play the alto sax. I am also a swimmer and a track runner. i am planning on being a physicist, so i want to go to a really good mathematical/scientific college like MIT. But the thing is, i cant seem to find a college that excels in science, athletics, and music. I am wondering if i should just make music a hobby and just exorcise for fit, considering college will already be stressful.
