Wikipedia’s defines creativity as a mental process involving the generation of new ideas or concepts, or new associations between existing ideas or concepts. (Which, by the way, is much better than Merriam-Webster’s attempt, defining creativity as “the quality of being creative”. In Britain that is called sarcasm.)
But where does creativity come from? I am most creative when my mind is calm and not overwhelmed with thoughts, anxiety or other excessive mind-chatter… usually when I am meditating or engaged in another mindful activity, such as jogging or taking a shower. The creative inspiration appears to flow out of this stillness.
