The Adventures of Tintin

Captain Haddock: I thought you were an optimist.

Tintin: You were wrong, weren't you? I'm a realist.

Captain Haddock: Ah, it's just another name for a quitter.

Tintin: You can call me what you like. Don't you get it? We failed.

Captain Haddock: Failed. There are plenty of others willing to call you a failure. A fool. A loser. A hopeless souse. Don't you ever say it of yourself. You send out the wrong signal, that is what people pick up. Don't you understand? You care about something, you fight for it. You hit a wall, you push through it. There's something you need to know about failure, Tintin. You can never let it defeat you.
