Which got me thinking - if we look at things from a different perspective, how can we apply this sort of approach in work, in church - without trivialising core activities?
The answer, I think, lies in two key elements.
Firstly, ensuring that we don't lose sight of our objective (in this case encouraging people to use the stairs).
Secondly, and probably most importantly, to look at the required activity from the viewpoint of the participants. Lecturing people about the value of using the stairs would have had some impact, engaging them and allowing them to express themselves is clearly much more successful.
