This morning I was sitting in the train from Zurich to Frankfurt listening to Tom Peters’ audiobook "The Pursuit of Wow". After a while he talked about change and that change would only take nanoseconds, but to maintain it would take years.
It took me also a while (fortunately the trip from Zurich to Frankfurt by train is long), but then I thought he was right. A decision to change happens immediately. After that, it is developing the correct habits and putting them into play.
