Since you are part of the planet, and also part of the entire universe, by your making yourself a more joyous and serene person, our planet and the entire universe is automatically a more joyous and serene place. By your reacting in an elevated manner, the world has become a better place. Let this thought empower you. This will broaden your feeling of self-importance and increase the value of what you say and do.
