First, what Don said: the breadth and depth of the ECs you see on here are pretty strong. Granted, it's what necessary to get into the best schools, but if you want to get into your school or A school, then that doesn't need to be your goal. You'll also see at interviews that a lot of people are extremely weird. If you're simply not strange in person then you're ahead of the pack.
LOL that is comforting. Now I really feel like I have an edge.
