“Tu Mu closes with a note of warning: ‘Just as water, which carries a boat from bank to bank, may also be the means of sinking it, so reliance on spies, while production of great results, is oft-times the cause of utter destruction.’”

Sun Tzu
The Art of War

“I would not expect to be able to sit with you in 12 months from now and tell you that we are at victory or near victory or even close to victory. What I would say is I would hope to be able to convince you we have an organization that is now focused and moving in the right direction with the right culture, so that you could then believe that this is the kind of effort that could be successful.”

My Share of the Task: A Memoir

“A master in the art of living draws no sharp distinction between his work and his play; his labor and his leisure; his mind and his body; his education and his recreation. He hardly knows which is which. He simply pursues his vision of excellence through whatever he is doing, and leaves others to determine whether he is working or playing. To himself, he always appears to be doing both.”
