When someone proposes a "brainstorming" meeting I feel like a rabbit in the headlights - probably because of the pressure to produce ideas on demand. My best ideas tend to come when I'm least expecting them - in the middle of the night, or in the shower, or just staring out of the window, or chatting with people casually. I think I need to be in a relaxed state to let my mind wander, whereas "brainstorming" feels like my mind is being whipped into a storm.
Anyone else?
