OldPharm, totally agree with you....
I think one of the best things you can do is participate in activities YOU LIKE and you BELIEVE IN, not just for the sake of looking good on the application. Find things that you feel are interesting and that you like because if you do activities that look good on paper and only for that reason and they ask you during an interview chances are you'll get caught for being lackluster about them. You won't have anything meaningful to say about the activity during the interview. Believe me I've been questioned at just about every interview about at least one of my activities. I think what matters most is exploring what you find fulfilling whether it be in research, community service, sports, culture, leadership. I believe that no matter what activities you do, the skills you develop and the professional/personal experiences you encounter will somehow be transferable and beneficial to you in applying to pharmacy school and during school.
