What's my next goal?

I'm always jumping around games and find it hard to finish the majority of games I start. But its not like I haven't before. Ive played og wotlk, the first classic servers and now anniversary. And I've never gotten any of those to max level.

I always get bored and want to start something new so I either make a new character or start a new phase of whatever I'm into at the time.

I REALLY want to hit Max level on this account.Im playing priest, I love the world. Questing has been fun albeit a tad grindy sometimes. I'm speccing for shadow.

I got through the first 30 by always setting myself a next goal. New wands, New abilities and eventually my mount.

Now I have my mount and I'm lost. I'm trying to grind some dungeons but it's near impossible to find groups at this level for some reason. (I'm not doing fucking gnomeregan again)

So my question is.. what's my next goal? What is the immediate thing I should be chasing. Why should I hit those next few levels?
