Outcomes by themselves don't really have an unambiguously positive or negative effect on your happiness. Yes, there are some outcomes—you get a terminal disease, or your child dies—that are pretty extreme, but let's leave those out. But if you think about it, the breakup that you had with your childhood girlfriend, or you broke an arm and were in a hospital bed for two months, when they occurred, you might have felt, “Oh my goodness, this is the end of the world! I'm never going to recover from it.” But it turns out we're very good at recovering from those, and not just that, but those very events that we thought were really extremely negative were in fact pivotal in making us grow and learn.
