Walking and thinking for me somehow gets things flowing in my mind and I'm able to work out ideas. Often when I'm trying to figure out how a difficult situation or problem should be handled I'll go for a walk and talk to myself.
In order to be open to creativity, one must have the capacity for constructive use of solitude. One must overcome the fear of being alone.
One of the areas I'm working on with a group of teachers at the moment is an adaption of the professional learning strategy Lesson Study. This involves a group of teachers planning a lesson, observing while one teaches the lesson and the evaluating how it went and planning for the next lesson and so on. This is taking up a chunk of my current solitude looking for ways to make this successful for the teachers involved.
