My laziness. I think I would've accomplished so much more if I wasn't lazy, to be honest. I always come up with good ideas and just sit and think, then don't do anything about it, unfortunately. I am actively trying to change this!

The more shallow answer is my calves. They are just disproportionately large, so much so that I have a hard time finding boots that fit over them. I'm also actively trying to slim them down!
