Breakfast Topic: Finding motivation to level or grind

Arrowd of the US Cairne server has a question

: How do you keep leveling without getting bored, abandoning a character, or rerolling? She says that she's had around 14 characters, and she's never managed to stick with one past about level 45. She always gets bored, and she wonders if there is a way to avoid it.

Now as I've mentioned before, I've leveled a lot of characters myself, and have a few 70s, but even I can sometimes get a little bit tired of the grind, and sometimes even I need to make up goals to keep myself focused. Sometimes I even need it for my level 70s if I'm running low on gold or raiding supplies. In that way, I can definitely feel where she's coming from, but I do (usually) manage to keep myself motivated.

Sometimes, for me, the Motivation is pretty simple. For example, on that Shaman I'm leveling, what keeps me going is the prospect of getting some sweet Dual Wield action going. I'm actually having a lot of fun with her, so I don't need to focus on it too hard, but the idea of imagining her with 2 axes enchanted with Windfury is a mental picture that is too awesome to put into words. I mean, we're talking cover of a Dragonforce album awesome.

So now I turn the question over to the rest of you. Whether it be leveling on a lowbie or grinding on a 70, how do you keep yourself motivation when the going gets tough and you get tired out? Is it the promise of a new skill? A new piece of gear? What keeps you charged up and logged in?
