Ideas for a tattoo that represents strength / value?

Im getting a tattoo in a couple of weeks and instant messaging for something to represent force / value. The only thing is I do not want it to be in Chinese, Japenese, and Celtic. Im looking to move from a command or something in that line. I have some ideas looking for something that might fit better to me.

a lion? always says that a lion is a symbol of strength and courage:)
