When you care too much, you get hurt a lot, so in order to stop hurting you need to care too much. Of course, a lot of people might claim there is a logical fallacy there but let me explain.
When you care too much, there is a higher chance of hurting too much, right? And everytime you get hurt, it’s like a dagger sent through your heart, and even if you don’t let others see it, the immense pain is there. You feel it. With time the wound might heal (or it might scar over) and you move on. You care again, and you get hurt again, and the cycle continues; the more you care, the more you get hurt. But then a point comes when your heart is so scarred over that you don’t feel the pain anymore. Your threshold for pain increases, and suddenly the pain doesn’t feel so bad.
Think about it in another way. Burnt skin hurts for some time but when the sensory cells die do you feel anything?
So in other words, When you care too much, you get hurt a lot, so in order to stop hurting you need to care too much.
Do you agree or not?
