My source says your extracurricular activities should be focused on the things you are passionate about and have been involved with for years (the longer the involvement with your favorite activities, the better). Colleges don’t really care what your activities are, just as long as there is in-depth, long-term involvement. Because college admission officers prefer students with long-term commitment to their activities, they look for students who work their way up into leadership roles. If you are involved in an activity you are passionate about for years, the expected progression is to go from simple participation to leadership. Being a leader is very appealing to admission officers because colleges need leaders in every field of interest.
