Humility

Humility makes a whole lot of things possible, -
None more important than a single humble question: “ What am I missing ?”
Good leaders constantly worry their limited ability to see. To rise above limititations , good leaders exercise judgement, which is a different thing from intelligence.
Intelligence is the ability to solve a problem, to decipher a riddle,  to master a set of facts. Judgement is the ability to orbit a problem or a set of facts and see it as it might be seen through other eyes, by observers with different biases, motives, and backgrounds.
It is the ability to take a set of facts and move it in place and time - perhaps to hearing room or a courtroom, months or years in the future - or to the newsroom of a major publication or the board room of a competitor.
Intelligence is the ability to collect and report what the documents and the witnesses say ; judgement is the ability to say what those same facts mean and what effect they will have on other audiences.
