Not really, at least for me because even if someone else "doesn't use it," you still have the satisfaction of knowing you're following your well defined value system to the letter, and there's nothing you could have done anyway without acting outside your value system.

Dale Carnegie was writing about this stuff decades ago, so another way to look at it, if you really need a reason other than "feels good," is it gives you a tremendous advantage in social situations of all kinds. You're more likely to "get what you want" in the end, though that kind of thinking is not really the point imo.
