I do, but under certain conditions:

It's a fun group. Loose, fun, has a sense of humor. I don't need things to be perfect, but neither do I want disastrous. It's a game. Game's should be fun. But it also shouldn't be work. You need to balance the two.

Which is where number two comes in. I don't grind. I try to mix in other things: triad, racing, maps, dailies, Atmas, etc. I always try to have other things to do so that I'm not grinding. Because the grind is what takes a toll.
