So is money. Not many people know clearly the disadvantages of having a lot of money. If you don't either, I'll tell you. Having much money makes you become a lazy person. Instead of working hard, you'll just spend your time buying luxuries because you think that you've reached your biggest purpose: earning a lot of money. Furthermore, people who hace a lot of money will have a different outlook on life. They'll look down on people who can't have as much money as they do. This'll lead to an ever-lasting disagreement between high-class people and low-class people.
Having a lot of money isn't a bad thing at all, only when you know how to control it. Therefore, think carefully before doing anything with your money.
