What's Wrong?

OK, I here's the deal. This year alone I applied to be on exec, Rho Gamma (Chi), and Peer Mentor and was rejected all three times. What is wrong? I asked why I wasn't chosen and everytime they tell me that it wasn't me as a person and they had a lot of very qualified people applying. I mean obviously there is something wrong with me to be rejected 3 times in a row. Will I never be good enough for these people? I mean I am graduating in December so it's not like I wouldn't be here to do it. I have the time to do it and am very qualified.

BTW, a Peer Mentor leads a class of freshmen of about 15 - 20 and is like a counselor to these students.
