People will piss you off—it’s part of life, and feeling frustrated is a natural reaction that you often can’t control. But what you can control is how long you let that feeling control you. Don’t allow yourself to become stuck in feelings of anger or resentment! That will only take you down a negative path, one that will let the anger in you grow. Instead, feel pissed off, acknowledge the wrong that was done to you, and then start to let it go. Holding anger inside will just poison your happiness.
