So often we carry around this idea that we have been harmed by what someone said, while most of the time it is our perception of what was said. If you let yourself be blown off course by all the things you hear and then take offense, then you are forever reacting, forever harmed.
If you cease to perceive what is said as a personal attack, you will cease to be harmed. There is no peace or happiness reacting to all the shit that happens. Cast away the worry and anger. You are only harmed if you let yourself be.
