The New York Observer:

Colin Powell makes the case: pissing people off is both inevitable and necessary. This doesn’t mean that the goal is pissing people off. Pissing people off doesn’t mean you’re doing the right things, but doing the right things will almost inevitably piss people off.

Understand the difference.

I piss people off on a regular basis. It’s rarely my goal but I honestly don’t care if it happens. This article explains it well.
