At his trial in December and again Wednesday, Phelps said he's learned a lot about himself. Asked what he discovered, he replied: "I am who I am. I've said this a lot over the last few months: I'm perfectly imperfect. I'm a human being. It's like, if I have all this energy and I'm annoying and you don't like that, well too bad. That's who I am. And I'm OK with that. I like myself for who I am."
