One point in the article I'd put another spin on is the adaptability part. While I totally agree with the author there, another symptom of this is that less "adaptable" people are prone to giving up with the phrase "I don't know" when they are faced with an unknown problem.

In most cases, "I don't know, but let me try and find out" would be a way better approach to things (as well as a more useful mindset overall). I've literally solved bugs that were ignored due to "not enough information" for weeks because the original assignee wouldn't even launch a simple grep query and apply some simple predicate logic.
