This is a great video of Jon Kabat-Zinn talking about mindfulness.
There's a great passage starting around the 48 minute mark about meetings and what it is to really show up. He does a beautiful explanation of the difference between discussion and dialogue.
This really resonated for me, and reminded me how much creativity can suffer when we play power games. And how much creative juice we can find when we create a more mindful and level playing field. When we manage to suspend our egos, get into a zone of not-knowing, we can get a kind of emergent intelligence bigger than the sum of our parts.
