"LIVE TO FIGHT ANOTHER DAY
Really though, it is most important for INFJs to remember to take care of themselves. The passion of their convictions is perfectly capable of carrying them past their breaking point and if their zeal gets out of hand, they can find themselves exhausted, unhealthy and stressed. This becomes especially apparent when INFJs find themselves up against conflict and criticism – their sensitivity forces them to do everything they can to evade these seemingly personal attacks, but when the circumstances are unavoidable, they can fight back in highly irrational, unhelpful ways.
To INFJs, the world is a place full of inequity – but it doesn’t have to be. No other personality type is better suited to create a movement to right a wrong, no matter how big or small. INFJs just need to remember that while they’re busy taking care of the world, they need to take care of themselves, too."
