It is amazing to me how often people react violently to the thought of change. In my business, I am paid to help people realize that there might be a better way to do something. Often I encounter resistance to the mere thought of doing something differently. And that's okay. It is human nature to be a bit wary about some stranger coming in and telling you, essentially, you're doing it wrong.
"What do you mean I am doing it wrong? I've been doing it this way for 20 years and it hasn't been a problem!"
Working in this area of personal protectiveness is often challenging. I like to engage people in discussions of what they think can be done differently to increase their effectiveness or make their job easier to do. When you have your conversations from someone else's perspective, from their viewpoint, it is often easier to effect change.
There are often many good solutions to a problem. Remember you do not have to be the one to develop the best way. Collaborative discussions on how to improve a process or solve a pressing problem usually result in a better solution that is trusted and supported by the person you are working with.
Even when they look like the charming fella in the picture above the moment you mention "Change."
