You can ask yourself to keep your trustworthiness, but you cannot request others to show trustworthiness towards you. You can tell yourself to treat people well, but you cannot expect other people to treat you well. However you treat people does not mean that people will return your kindness. If you don’t understand this fact, you are bound to reap untold disappointment for yourself.
