The Rewards of Coaching...

Satisfaction comes with a sense of accomplishment and contribution towards a worthy cause, mission, or unified interest that ultimately achieves something. Happiness comes with a sense of satisfaction, comfort, and possibly even pride in successful accomplishments or contributions to achieve that happiness.

I am both satisfied and happy about my first volunteer baseball coaching experience.  Watching and helping the players grow, gain skills, build confidence, and lead with sportsmanship, gives me pride as a contributor to their individual and collective achievements and accomplishments.
