Im at a crossroad..
Well I would say it really depends on what you’ve done already.
I have 2 characters at level 80 with full exotics, and I feel like I’ve got tons of things to do, in particular the various storylines, map completion, I still haven’t done all the dungeon paths, I’m levelling 4 other professions and have plans to make the final 3 at some point after that, I do the guild missions with my guild about once a week, play WvW….
“Life’s a journey, not a destination.”
Haven’t done a single dungeon yet
I highly suggest trying the dungeons out with a group of friends. The dungeon pugging community can be very toxic and off-putting, so running with at least a friend or two is ideal, if you want to have a good time. Sure, the rewards may not be that good, but the experience is a reward on it’s own.
Planning on upgrading to a GTX980ti by late 2016
Fractals as well.
I personally find enjoyment in often doing relatively pointless but relaxing activities. I’ve done PvP at pretty high levels, WvW roaming, high level fractals, etc., and it can be relatively demanding for something as relaxing as a video.
So for example, the other day I killed a bunch of oakhearts to finish off my plant slayer achievement, and entertained myself by dodging all their attacks which have huge telegraphs. Playing a few rounds of the daily activity is actually a ton of fun. Earlier today I did a good old fashion farm with about 10 people just killing karkas and getting tons of phat loot. Getting 100% on a single map on an alt is fun because it just gives you a relaxing environment to play with traits and under-used utilities on a class you don’t know that well. I got my crafting up to 500 on a track I’ve never had a need to use. All of this is totally mindless, and totally relaxing. 
Edit: I left out a major part. All this just relaxing and having fun means that I don’t grind anything and yet still rake in money, mastery points, mats, etc. A watched pot never boils. Next time I want to do something “real” like make a legendary, I can just buy it with all my screwing-around money.
