Quote by James A. Michener, attributed
The master in the art of living makes little distinction between his work and his play, his labor and his leisure, his mind and his body, his information and his recreation, his love and his religion. He hardly knows which is which. He simply pursues his vision of excellence at whatever he does, leaving others to decide whether he is working or playing. To him he's always doing both.
Summary
This quote suggests that a true master of living does not differentiate between different aspects of their life. They seamlessly blend work and play, labor and leisure, mind and body, information and recreation, love and religion. They are driven by their pursuit of excellence in everything they do, so much so that it becomes indistinguishable whether they are working or playing. To them, every activity is an opportunity for growth, fulfillment, and expression of their passion. It is up to others to determine whether they are working or playing, as for the master, it is both.
