So, what's good for the soul? It varies. Sometimes you can be introspective, sometimes you must devote yourself to making society a better place. People are always saying they want to be happy, and yet, happiness eludes them. Do they seek possessions that fail to bring long-term happiness or experiences that are fleeting? Then, on to the next thing that might give them a small amount of happiness for a short time.
I've found true happiness can be found in service to others, even in small things. Not all of us can do great things. But we can do small things with great love.
