Whiteboards make it easy to be wrong, and that’s a good thing.
When we’re solving a hard problem, it’s unlikely the first solution we come up with will be good enough. We need to churn out a number of ideas, sort the good from the bad, and then refine the few until we end up with a solid answer.
A whiteboard is an open canvas. It invites us to try, to experiment, to be bold, and most importantly, to be wrong. With a quick wipe, any bad idea is erased, and any new idea has space to emerge.
When I’m stuck, I quickly find myself seeking out a big blank whiteboard.
