Outliers exist, and you can build a team of them (it's been done, it will be done). The "trick" is to get people to "work" on something they love doing and are proud of.

Also, and Carmack nails it, people are different. You might think it's unhealthy, or unnatural, but some people are obsessive, perfectionist, focused or just really passionate about something. Also, some people are just better organized. Again, Carmack's right, you probably can't be at your peak for extended periods of time, but there's plenty of things you can get done that don't require your peak.

When this issue is raised from concern of people being taken advantage of, fine, I agree. But just because some people can't do it, doesn't mean no one can (just look at the extreme range of physical and creative abilities that people have). And, like all other life style choices, what's the point of judging other people?
