You have enemies? Good. That means you've stood up for something, sometime in your life.
-Winston Churchill-
I'm not sure if the attribution is correct (it may be--I just haven't checked). Regardless of whose words these are, the point is sound. Change is friction and friction is pain. Those who move cheese and rock boats are bound to piss at least a few people off--it just comes with the territory. But so what? Why is it so important to a nice person? I'd rather be an effective asshole than a pleasant bystander.
