4. Your Income

Never ever tell another person how much you earn. Only a handful of people should maybe know what you earn and they should be the people you share the workplace with, and maybe not even them. You don’t want everyone to know what you earn and where you stand financially. If you are rich, it will come off as bragging and, if you are not so rich, it will come off as whining. It can lead to changing the relations you have with other people in a drastic manner. When a lot of people know how much you earn, it will definitely change their behavior towards you based on their financial standing.
