I think "strength" can have remarkably subjective definitions. I see strength as being the ability to get up and do what needs to be done (with apologies to Garrison Keillor). This kind of strength involves ethics, stamina, perseverance, selflessness, and other virtues that direct purposeful action. It's core component is resolved action to do what you know to be the right thing.
