Few aspects of the admissions process tend to fray the nerves like pulling together an activity list in your senior year and reviewing your extracurricular pursuits. Almost no one feels they compare well with their peers. This feeling is only compounded by articles about other applicants taking an 8-week jaunt to Bolivia and doing ground breaking research on some strange virus, or playing with the New York Symphony in Beijing before hiking up the face of K2. These applicants do, probably, exist. But, they shouldn't deter you from taking pride in whatever it is you enjoy and excel in.
