It is the moment I look for on my training courses. It is when participants switch from general interest in the topic or material to a moment of clarity about where they are now, what they want to be able to do and what stands in their way. For me this is when teaching and learning come alive because we have clarity of purpose, a goal which provides both motivation and a clear end point and a challenge that we can sink our teeth into.

When we reach these conditions we can enter into a space of joint experimentation (as my colleague Søren Willert would call it) where neither of us necessarily know what is going to happen but we have confidence that our efforts will be worthwhile.
