comes from Zhuge Liang's "The chapter of precepts": "A gentleman's journey: quiet to cultivate one's morality, frugal to cultivate one's morality. Not indifferent, not clear-minded, not quiet, not far away. You have to be quiet before you can learn. If you don't learn, you can't learn widely, and if you don't stay still, you can't succeed. If you are slow, you can't study hard, and if you are dangerous, you can't be rational.
