I think your feelings are sort of like "muscle memory" after so many years of putting everyone else's needs ahead of your own. I like the way Kindeyes described re-framing the situation.
That said, there is one universal truth that can never be denied, the light and the way to happiness and fulfillment, one undeniable fact to which we can all synchronize our individual moral compasses, and the glorious truth is this: one must never, NEVER, feel bad about sexy new boots.
