There is much busyness in business around change. Change theories, change consultants, change strategies, and lots of pretty diagrams. Don't you know "change is the new constant"!?
Most of this is displacement activity to avoid actually having to change. It's all about changing things outside our selves: structure; processes; or, more commonly, other people!
But real change doesn't happen until you do it. Until YOU do it. Until you think differently, speak differently, act differently. Until you have different conversations with your colleagues, with your boss, with your clients, with your customers.
Why not start now?
