One of the hardest things to decide when coaching youth soccer players is when you should praise versus when to criticize. The best rule of thumb is to always remember the kids age and not take any situation too seriously. 

Remember to offer both praise and criticism when running youth soccer drills. It is suggested that children learn best with a 5:1 ratio in favor of praise. If you criticize too much, your players will get discouraged, irritable and scared to try new things.
