Should I rewrite everything in third person?

Don't let Twilight bully you into changing the name. Jasper's a lovely name, and so is Edward and Alice. But they're so common that no one will no if you use them. And first person POV is fine. It doesn't have to be in third. But if you feel more comfortable writing in third, by all means, change it. I guess what I'm trying to say is, it's up to you.
