Don't wanna attack your way of playing or anything, but i'd say you're rushing the game.
Take your time to enjoy it, do side-quests, explore the world, do some old trials and dungeons. Heck you haven't even unlocked the chocobo and it's a lvl 30 quest.
I'm level 57 with my main and i'm not even close to reach Heavensward, don't really care either, just taking my time doing what i come across.
There's so many cool things on the journey to max level i think it's a waste to rush them so you can reach the end-game, so that you'll come back to them later when you're bored, you won't find them any fun by then because you've tried the newer, more sophisticated content.

My 2 cents.
