Unbundling

I first came across the term 'unbundling' when reading Supporting future oriented learning and teaching - a New Zealand perspective. For some reason that one term has stuck in my mind more than others from this publication. I wonder if it's because it seems to have so many layers and migt explain why change in some cases is so difficult.
I'll start with myself. To 'unbundle' myself as Principal. Here's my thinking. First of all, I have ideas of what I think a Principal should be and how they should act, what they should do etc. Then there are the ideas and expectations of others - students, parents and colleagues. Where do these expectations ckme from? Usually from our previous experiences right? I've watched and been around several Principals in my time. I guess along the way I've decided that that is what you do and how you behave. I'm not entirely sure that I fit the typical mould, if there is such a thing, but I attempt to be the type of Principal that I believe others would want me to be like. I sometimes ask myself if I'm the type of Principal I would want to work for. Sadly, sometimes the answer is no!
So, unbundling. Where would or should I start? After all, I am the only thing I can change. I can only control myself. What one thing could I attempt to change about myself that might have a positive effect on all those around me? I have no answer, yet. But being aware that to bring about change at all levels of school, to unbundle some of the existing practices that might be holding us/me back, I might need to reflect on what it is I do as Principal, and what I don't do and begin with one idea or behaviour to focus on.
I'm thinking that in order to bring in something new, I will have to let something go. That's the whole idea of unbundling. I want to go back from my sabbatical time, changed slightly, for the better.

What would you wish to unbundle?
