I recall you posting a quite from James Michener years ago...about the master of the art of living combining his passion and his work. I just googled it b/c I couldn't remember the quote exactly, just the sentiment of it.
Here it is: "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 is always doing both."
Sounds like you've accomplished that very well...congratulations! May we all be so lucky.
