I think taking things personally is useful if we have the intention to use our triggers as a catalyst for our healing journey. But if our intention is to not use them, then the below quote might helpful.
“Whatever happens around you, don’t take it personally… Nothing other people do is because of you. It is because of themselves. All people live in their own dream, in their own mind; they are in a completely different world from the one we live in. When we take something personally, we make the assumption that they know what is in our world, and we try to impose our world on their world.
Even when a situation seems so personal, even if others insult you directly, it has nothing to do with you. What they say, what they do, and the opinions they give are according to the agreements they have in their own minds…Taking things personally makes you easy prey for these predators, the black magicians. They can hook you easily with one little opinion and feed you whatever poison they want, and because you take it personally, you eat it up….” –Don Miguel Ruiz
The different worlds Don Ruiz speaks of can be best explained here.
