Resist manipulating how people see you. Do not try to impress anyone with your style, intelligence, creativity, wit. Interact with everyone simply. Be present and other focused. When you feel that you have tried to manipulate how someone sees you, write it down. At the end of the day reflect on each of these instances and pray that God will help you resist the temptation in similar situations in the future.
