Many years ago one of the best books on Continuous Improvement (Lean) was written, The Toyota Way. Still today this book is studied and referenced in many different operational excellence ventures. In the book author Jeffrey Liker discusses 14 management principles that are important in a Lean Strategy. While these 14 principles are quite important one of the common themes you may think about and hear through the book is the idea that "doing something is always better than doing nothing." Amelia Earhart's quote above is a perfect reminder of this powerful behavior; "The most effective way to do it, is to do it."
It is quite common for all of us to dream of an imagine the absolute "perfect" situation when looking to improve, but, perfect is not always the correct way to imagine. Perfect is hard to achieve but better can always be achieved. If your moving in the right direction it doesn't matter how far you move just that you keep moving and as Amelia and Mr. Liker's book hints sometimes, moving in the right direction requires first that you get started.
