Listen first, speak last.
Peter Drucker in The Effective Executive, page xxiii
I did not expect to find “listen first, speak last” in a book on business leadership. But there it was. Peter Drucker elevated it to a rule for executives to follow.

This didn’t play into my stereotype of the brash, bombastic, self-assured, influential executive. Aren’t leaders supposed to be the boss and have people do their bidding? At least that was the excuse I used when I tried to reason why some are leaders and others are followers.
