Boat Metaphor

This is a hybrid of the Russ Harris' boat with monsters metaphor and weather as emotions metaphor to explain commitment to values. 

You have an indestructible ship that only you can steer. You have serveral compasses on your ship (that represent different values). Because there is nothing that can destroy your ship, and you're the only that can steer it, the only thing that moves your compass needle(s) away from the direction you need to go is you. The weather is your emotions- sometimes choppy, sometimes calm, but they can't actually move the boat. The animals and the sea monsters are your thoughts- sometimes scary, sometimes pleasant, sometimes beautiful, sometimes terrifying, but they can't actually move the boat.
