Chicken or the egg - Motivation or Action

I always thought that the motivation to engage in a task was required before action took place. However a respected colleague and friend of mine once noted that "sometimes action preceeds motivation." It seemed simple but it was very insightful. Think of the person that you want to be. Then take steps to be that person. Each step builds confidence, which in turn leads to greater motivation. Do it, don't wait for it!
