“You feel your strength in the experience of pain.”

“The fact that you can feel pain like this is your greatest strength.”

“People are afraid of themselves, of their own reality; their feelings most of all. People talk about how great love is, but that’s bullshit. Love hurts. Feelings are disturbing. People are taught that pain is evil and dangerous. How can they deal with love if they’re afraid to feel? Pain is meant to wake us up. People try to hide their pain. But they’re wrong. Pain is something to carry, like a radio. You feel your strength in the experience of pain. It’s all in how you carry it. That’s what matters. Pain is a feeling. Your feelings are a part of you. Your own reality. If you feel ashamed of them, and hide them, you’re letting society destroy your reality. You should stand up for your right to feel your pain.”

“There is no shame in what you are feeling, Harry,' said Dumbledore's voice. 'On the contrary... the fact that you can feel pain like this is your greatest strength.”

“It is a Siren's burden," she whispered, "So much strength, so much pain. You will feel the weight of humanity on your shoulders, though you are only partly human yourself. Soon you will not have any traces of that left.”

“In the end, some of your greatest pains become your greatest strengths.”
