Six Thinking Hats, by De Bono

Six Thinking Hats, by Edward De Bono.

It's easy to fall into a particular pattern of thinking. De Bono proposes a method where various thinking styles are associated with hats of different colors: white (data), red (intuition/emotion), black (pessimistic), yellow (optimistic), green (new ideas), and blue (process). By explicitly applying different perspectives, you can nurture an idea to fruition, and you can get a fuller picture of the consequences of it. While I don't think the whole thing is as amazing as the author thinks, it is a useful reminder to help broaden your thinking.
