It's a hobby. You can never be 'satisfied' with a hobby, or you're missing the point. If there is nothing to do, no way to improve... it's no longer a hobby.
I've seen magnificent tanks in the homes of well off people who know _NOTHING_ about reefing... they're paying a maintenance company to handle everything, to them, it's just something neat to look at. It's not a hobby, it's an expensive decoration.
Might as well get a DVD of a nice reef, and play it in a loop.
To me, reefing has always been a hobby. I know fishkeepers that think of their finned friends as pets... I guess that's true, in some ways. My pets are my dogs. We've got three, two great Pyrenees, which are absolutely members of the family, and working members of the family, at that. The other is a shih-tzu. Basically, a dust mop that's happy to see you when you get home. Fish? Those are part of my hobby.
A hobby is something you _DO_ for enjoyment. Golf, shooting, hunting, fishing, boating... those are hobbies. Reefkeeping is, as well. I've been at this for a couple of decades now... and I'm still learning, still finding new and better ways to manage my reef. There is ALWAYS something that you could be doing to your reef. After all, that's the point, isn't it?
