“Human beings are most creative when we get time by ourselves and then time with one another. The way to maximize creative potential is to flow between being alone and being in a group, and back again. When you’re alone, you’re essentially building a woodpile in your brain. Then, when you join a group, you’re igniting a shower of sparks that might light it up. Of course, you sometimes need to go be alone again in order to let the sparks you’ve started generating get close enough to the wood.”
