Most of us aren't total black holes, but when we fail to give thanks for what happens in our lives, we can get hung up in bitterness that prevents us from developing emotionally and spiritually. If we fail to grow, the light inside us grows dim. Gratitude is an inner light that we can use to illumine our souls. The more we are thankful, the more light we experience and the more we shine forth into the world.
