Grinding, and how much it sucks o_O

Every MMO has it, every RPG thrives on it. But it gets utterly boring... for me anyway o_O

Ragnarok Online grinding used to be fun, but it bugs me now. For a lvl 94 transcendant, you have to spend probably a month of large group partying to reach 99, and you don't get a whole lot of stat increases from it, so the grinding of RO just isn't fun anymore.
WoW quest grinding was reasonably fun, at least in the Outlands I could just go to another area if I got tired of a certain one. But now I'm lvl 70 (No Lich King expansion for me) and now I have to honor grind and gold grind, and it's gotten mostly boring again.
There's another MMO I can't remember that I actually enjoyed the quest grinding and monster grinding. One of the classes was called a Force Shielder, I remember that. The grind got boring though when the quests started requiring stuff like killing 99 Wriggleleaves (pretty difficult to kill monsters, actually).

So how do we 1)Decrease the grind of our game, and 2)At least make the grinding fun?
