If you stand on your tiptoes, you won’t have a firm stance.
While you are straddling a position, you make no advance.
People who are willing to parade themselves off to the world have nothing of value of which to shout.
People who boast and brag are not necessarily worthy of the merits and accomplishments of which they tout.
People who think their shit doesn’t stink will never actually get the power that they want, no matter how much power they have.
All those folks exist within the Tao in order to say: that which remains (humility, the knowledge of how to get things done when you are not in power, steady footing, etc.) eclipses all that stuff, even if it appears superfluous.
