Generosity is something I always try to carry because it's just good karma. Before high school, I went to a catholic school in New York City. They always taught us to be generous and they always had food drives the homeless people all around the city. That made me the kinda generous person I am today.
Remove materialistic people from your life! I know several materialistic people. It's kind of sad that material things rule their life. My car is faster, my house is bigger, my boat is better. Always trying to out-do the other person. I picture that life like being on a hamster wheel. You can never catch up. Cause unless you're Bill Gates, it's futile.
