To start with the online part, they've got to be a self-starter. They've got to be organized. This is not a world where someone needs to make sure you're in class. A lot of times, the lectures are taped, they give you a syllabus, tell you when things are due, and let you go. It's not for somebody that needs to be coddled. That kind of person would struggle greatly. The other thing is curiosity. You could go through the classes and just do what they say. You can get a good grade. But you need to be curious about what's really going on, dig further, and understand why, as opposed to what.
