Some of our most creative work gets done in downtime–waking from a nap, taking a walk, daydreaming in the shower. (Writers are particularly clean.) Downtime is when breakthrough ideas are delivered to us, unsummoned, when yesterday’s blockages somehow come unblocked. That’s because we treated ourselves to a little boredom and cleared our brains of the sludge of information. Try it.
