Sometimes, I get into predicaments and don't know how to quit a webtour or place people in breakout rooms. So I calmly start exploring possible solutions, talking about it as I try to recover. While doing so, I also talk about the importance of exploring close enough to the edge to fall over it frequently. I model tolerance for error, learning from error, pushing the envelope of tech. Indeed, I've found that the earlier I can break something and fix it in public, the better. We talk about what works and what doesn't, discard what doesn't suit our purposes, push a tool further if it helps us learn together. It requires regular doses of humility to abandon what seemed like a bright idea at the time.
