Hey, you brought up another one: not a black-and-white thinker!

Things are not only their extremes and the opposite. Hence why "balance" is actually an extremely undervalued quality in a person, and it was very apt of the author to call it out.

I think your observation about thinking in black and white is a good observation. However, you still haven't answered the OP's original question. And adding your observation to the list, these sorts of things are still required at large organizations.
