#2: Helping Helps
Some people see life as a zero-sum game. This means that the only way for you to gain is for other people to lose. People who live this way don’t see the point in helping others because they argue that the only thing that matters is doing what’s best for you.
What they fail to realize is that life is not a zero-sum game; often, doing something kind for someone else actually ends up benefiting you as well. Even if it’s not like a fairytale where the hero gets rewarded for his good deeds, helping others can help you by increasing your own happiness or emotional well-being.
