Leaders should never surround themselves with people who only tell them what they want to hear. Even though it’s tempting to exist in a positive feedback bubble, you need to fight this inclination and encourage independent thinking by others. If you are always the smartest person in the room and your opinions are largely left unchallenged then something is wrong. Sometimes the truth hurts, but it’s better to deal with reality than ignore it. In addition, it’s been proven that a group regularly makes better decisions than any one individual.
