People thrive on positive reinforcement. They can take only a certain amount of criticism and you may lose them altogether if you criticize them in a personal way... you can make a point without being personal. Don't insult or belittle your people. Instead of getting more out of them you will get less

If a player needed me to light a fire under him by turning the other team into a demon, he was lacking something I couldn't give him.
