Rejoice in the good fortune of someone else. By doing this you overcome the very human tendency to feel that there is a limited supply of happiness and someone else is getting your share. Express your happiness in a note or with a call. Celebrate others' joys in your prayers by praying for all the people being married right now, all the people welcoming a new child into the family right now, all the people getting a promotion right now, all the people relaxing on vacation right now, etc.
