Seth Godin from "Seth Godin on the Art of Noticing, and then Creating," On Being, January 24, 2013:
When I give a talk — at the end [I'll] say, are there any questions? And the only people who are raising their hand are raising their hand because they think they have a question the group wants to hear. They think that they have something to contribute.
Now what's fascinating about it is five minutes after we're done, everyone has a question. Right? Because now it's safe to ask your question because you're not going to be judged on the question that you're going to ask.
But the people who do ask a question have demonstrated to themselves that they have good enough judgment to be able to put something into the world that hasn't been said before. That's what makes it a good question. And that practice is something that we should learn and we should teach our kids, and we should teach our colleagues how to do it.
