What quote should i get with my brass knuckles tattoo?

I am getting a brass knuckles tattoo on the right side of my stomach/hip with four leaf clovers in the four holes instead of circles, I would like to have a quote with it, I was thinking of getting the quote "wolf in sheeps clothing" but I feel like people would think I am two faced if i put that. Or possibly "Savage By Nature"I want something meaningful, not so much to do with fighting but maybe courage or life quotes of some sort? I do not want something long though. Help please? thank you! :)
