I don't know.. I just feel that I'm not attracted to this game like I used to be. Anyone got any tips on how to "get addicted" again?

I played GW2 after about a week or two after the launch date and have been playing it avidly until about 2 weeks ago, when I hit Level 80 and full exotics. I still find the game fun, but I just seem to have run out of things to do. I want to 100% complete the world and work on a legendary, but I just don't feel it... Does anyone have any protips to just kind of get back into the game and enjoy it? I don't wanna force myself to do it but I still feel it'd be fun.
