Having kind-hearted people can be a gift, really, and they are rare. Most people change at the sight of money, and you'd discover how greedy they truly are. Many times, we must be careful who we are dealing with or working with, because, trust me, when someone works with a devil, what do you expect in return?
Working with the right people with good attitudes, especially towards money and who are considerate of others' needs, is the best thing one could come across.
