A little bravado never hurts, and it might make you feel pretty good. It never hurts to sing and dance. Don't invest all of your power into just one ring. Elves and dwarves have different ways, but that doesn't mean only one of them is right and that they can't be friends. No matter who you think you are and what your destiny may be, be prepared for surprises.
All power lies with the Earth, be it a garden or a volcano.
Listen to others. Never assume that you know what's best. When all else fails, stall. Know when it's time to say good-bye. Good advice can come from unlikely sources.
