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 education and his recreation,
his love and his religion.
He hardly knows which is which.
He simply pursues his vision of excellence
in whatever he does,
leaving others to decide
where he is working or playing.
To him, he is always doing both.
-- From a Zen
Buddhist quoted in
"Head to Head" by Lester Thurow,
Dean of M.I.T.'s Sloan
