"Nada pode ser obtido sem uma espécie de sacrifício. É preciso oferecer algo de valor equivalente."

"Ensinamentos obtidos sem sofrimento são desprovidos de valor"

"There’s no such thing as a painless lesson. They just don’t exist. Sacrifices are necessary. You can’t gain anything without losing something first. Although, if you can endure that pain and walk away from it, you’ll find you now have a heart strong enough to overcome any obstacle - a heart made fullmetal."
