Every person should play a sport at least once in his life. Sports teach us valuable life skills. A player learns to work with others on a team to achieve a common goal. He also develops the ability to work with people he might not normally like or whatever. Also, people who play sports have to manage their time carefully since they need to work out, practice, and handle everything else in their lives such as school, work, and family commitments. Finally, sports give a player the chance to release stress in a safe, healthy, and fun way.
