Let's being with an outright apology. When I read the article I also looked around a bit more of the site and came across the phrase "critical or negative thinking". It was a mistake on my part to think that came from the linked article when a 'find on page' shows the author didn't use the word negative at all. My blunder (which, as Donuel said, I may learn from!)

I didn't closely evaluate the article, though. Or at least, no more than anything else I read. Some level of critical review is second nature to me. But so is some level of other kinds of thinking. In the past month or so I have posted that I passed a lorry with the serial number MGL2560 and noticed it was (almost) a ceasar cypher of my surname, or that I passed a BMW 5350d and noticed that, upside down, that is POSES and so a hair's breadth from POSER. So a playful view of the world is also second nature. Then I was in Inverness recently where a lot of street signs are written in both gaelic and English and noticed the gaelic for church is similar to the French.   That's neither analytic nor playful. And so on.

So if the message of the article is simply don't stick to one way of thinking I am in complete agreement. But there's no reason to write a careless article to do that.
