“Gurus don’t use anger, harsh words, or fear to inspire their students. They realize that fear is a good motivator in the short term but over the long term it erodes trust. Criticism is lazy communication. It’s not constructive, compassionate, or collaborative. Look for ways to communicate so that the other person can consume, digest, and apply your input effectively. Offer them a “love sandwich” where you deliver a piece of constructive criticism between two tasty slices of positive feedback.”
