Unless you try to do something beyond what you have already mastered, you will never grow. – Ralph Waldo Emerson
Mastery should never feel it has been achieved, even the top pro athletes strive to reach new levels of accomplishments in their careers. If you believe you have arrived at the finish line in anything your growth has stopped, never stop growing and more importantly never dismiss an opportunity for transformation. I am not who I was yesterday and I am not who I will become tomorrow.
