Personally I work on an incredibly short term orientation, meaning "do whatever the kitten you want to do atm" - mainly meaning that I do whatever is in front of my nose and/or on my mind. I have a couple of longer term goals such as world completion (25% on highest level character, so definitely taking my time), acquiring certain armor skins, and hopefully, at some point, getting at least one character to lvl 80, but those are all optional things and I don't work actively and systematically towards them at all. These things probably end up happening almost by accident while I'm paying attention to something else.
I guess my biggest motivation for playing Guild Wars 2 is that I enjoy the world and the lore and the view. I'm 22 and a university student/circus teacher, and treat the game as a way of escaping deadline stress, adult stuff, and so on, and not something I need to "beat" or complete, so to speak. I think that's partly why I usually get motivated more by short-term goals such as 'completing this event' or 'getting to that vista' instead of long-term goals - creating those bigger goals and actively pursuing them would bring the stress and the pressure into the game, which would be counter-productive to the reason I play in the first place.
