There is no such thing as great wisdom in the world, just as there is no such thing as talent. What exists is triviality. If you keep doing repetitive things, you become an expert; if you do repetitive things with special focus, you become a master.
When brainstorming, improvising, jamming with others, you’ll go much further and deeper if you build upon each contribution with a playful “yes — and” example instead of a deflating “no — but” reply.
