Most often, innovation is not the result of a sudden moment of realization, anyway, but incremental steps toward improvement. Even groundbreaking paradigm shifts are most often the consequence of many small moves in the right direction instead of one big idea. This is why the search for small differences is key. It is such an important skill to see differences between seemingly similar concepts, or connections between seemingly different ideas. This even used to be the meaning of the word "new." "Novus," in Latin, used to mean "different," "unusual," not so much "genuinely new" in the meaning of "unheard" (Luhmann, 2005, 210).
