Care about your fans AND care about your business

Because you can't have one without the other. If all you want from music is lifestyles of the rich and famous, you'll end up alienating the people that got you there in the first place. People may not always be able to see sleaziness right away, but eventually the truth will come out. "Burn bright, burn fast," as they say.

On the other hand, if you don't take care of your business (of which music is certainly a part), then you'll burn out because you're not getting your needs met (rent, food, etc). Either way, the people who love you will lose out, and they're the ones who matter most.
