I think you guys are falling victim to the same oversimplification implied by the article. That is, that you can boil the CEO's success-potential down to a handful of traits.

The article is interesting, and there probably is generally value in the traits outlined but, no discrete set of characteristics is deterministic. Not only are other personality factors involved, but it also depends on the product, team, etc. The lazy CEO might be perfect when paired with the workaholic CTO.

Or, as others have put it, it's complicated.
