From the “What to Do in High School” section of MIT’s website:
Some students feel so much pressure to get into the ‘right’ college that they want to make sure they do everything ‘right’—even do the ‘right’ extracurricular activities. Fortunately, the only right answer is to do what’s right for you—not what you think is right for us. Choose your activities because they delight, intrigue and challenge you, not because you think they’ll look impressive on your application. Go out of your way to find projects, activities and experiences that stimulate your creativity and leadership, that connect you with peers and adults who bring out your best, that please you so much you don’t mind the work involved. Some students find room for many activities; others prefer to concentrate on just a few. Either way, the test for any extracurricular should be whether it makes you happy—whether it feels right for you.”
Just about every college I can think of would agree.
