I'm not sure that quite gets at it, though - because there's there are actually three branches here. Focusing on the problem, pretending there's no problem, and focusing on the solution.
I think that one who focuses on solutions can be positive-focused without ignoring the problem.
True, there are three groups of people. But the article posits that just focusing on the negative is problem. I'm saying that it isn't - that you have to focus on the negatives and on the problems in order to solve them. The article specifically says not to focus on the negatives and instead focus on the positives. How do you fix problems (negatives) if you don't focus on them and instead focus on the positives (things that aren't broken)?
