单选题 .  Do you want to live with a strong sense of peacefulness, happiness, goodness, and self-respect? The collection of happiness actions broadly categorized as "honor" helps you create this life of good feelings.
    Here's an example to show how honorable actions create happiness.
    Say a store clerk fails to charge us for an item. If we keep silent and profit from the clerk's mistake, we would drive home with a sense of sneaky excitement. Later we might tell our family or friends about our good fortune. On the other hand, if we tell the clerk about the uncharged item, the clerk would be grateful and thank us for our honesty. We would leave the store with a quiet sense of honor that we might never share with another soul.
    Then, what is it to do with our sense of happiness?
    In the first ease, where we don't tell the clerk, a couple of things would happen. Deep down inside we would know ourselves as a type of thief. In the process, we would lose some peace of mind and self-respect. We would also demonstrate that we cannot be trusted, since we advertise our dishonor by telling our family and friends. We damage our own reputations by telling others. In contrast, bringing the error to the clerk's attention causes different things to happen. Immediately, the clerk knows us to be honorable. Upon leaving the store, we feel honorable and our internal rewards of goodness and a sense of nobility.
    There is a beautiful positive cycle that is created by living a life of honorable actions. Honorable thoughts lead to honorable actions. Honorable actions lead us to a happier experience. And it is easy to think and act honorably again when we are happy. While the positive cycle can be difficult to start, once it's started, it's easy to continue. Keeping on doing good deeds brings us peace of mind which is important for our happiness.1.  According to the passage, the positive action in the example contributes to our ______.
