I changed recently the way I look at problems, instead of thinking I don't know, or I don't understand. I think that is more useful to think that I have a wrong model of reality, that way it helps to a) Acknowledge that I might have already assumptions that need be questioned b) Forces me to re-visit what I think I know c) Realising that accessing the right model is "just" a matter of finding what building blocks are misunderstood or missing in my model. I think the article suggestion fits this philosophy and it is a valid angle to attack a problem, in "model" terms "Find something that is like the hard thing but is easy" for me easy means, that is familiar to you meaning that is a model that you understand, meaning it is a model that you play and gives you the expected results.
