Love this bit: “Sometimes you’re stuck on a problem, and there just don’t seem to be any great solutions: maybe it’s related to a piece of code you’re writing, or decisions around how you’re going to market your app. Then, you start thinking about the problem from a wider perspective. You realize that you won’t need to even write the tricky piece of code if you architect it the right way, and that the marketing decision is one your friend (who has a knack for that sort of problem) would know how to tackle. You could sum it up as ‘taking a step back’ from the problem.”

Taking a literal step away tends to help. I've often realized new approaches or epiphanies when mulling a problem while walking or in the subway.
