The power of appreciation comes through actions. Feeling gratitude creates a wonderful internal experience; expressing it allows us to feel the full bloom of appreciation. Most significant would be our willingness on a moment-to-moment basis to find some aspect of every person and event to appreciate and then find a tangible way to express our gratitude.
