I'm not a natural fan of the phrase "I don't know." There's a possible humility in it that is commendable in a teacher, for example. But when we step out of the classroom and into life, I don't really want to not know. I need answers and I need them now!

But the hubris required to believe one "knows" seems, in the end, to be so destructive that it can become a great relief to just admit "I don't know," make a choice, and stay open to course correction.

Reminds me of a quote I heard to the effect: "if you want less stress, resign from being general manager of the universe."

Easier said than done, especially when you're not sure the real general manager is actually on duty.
