This article talks about taking time off from a difficult problem to get some distance and perspective so you can make a breakthrough.
I also really like the idea in here of “mental crop rotation” where you intentionally work on a different hard problem for a while to clean your head before you come back to the first hard problem. Actually, that’s from Kierkegaard. (I used to make fun of people who quoted Kierkegaard in college. 😂)
Creativity is about connecting dots. But if we try to force it, if we’re too focused on it, all we ever do is connect neighboring dots, resulting in a rigid grid of stale thoughts. To really see the interesting connections we need to get a new perspective and gain some distance. Then the truly interesting connections will reveal themselves.
