When you start to hear about a subject, concept, system or process it causes you to focus in a little bit deeper. Your hearing the "buzz" becomes an actual "on purpose" listening to what is being said.
As you listen more, you start to understand. When we understand things, we gain the confidence to start doing that activity required.
Through hours and hours of "doing" we can eventually master a task, action, concept or process. Or can we?
Do we really ever master something or will that pursuit of excellence continue to force us to hear new things?
And then the process starts all over again...
