If you are already burnt out now before cap. Take a break doing something else irl that catches your interest and then come back when it’s most comfortable.
It’s okay to have periods of low motivation. Just do what you feel like doing and take a break if you need to. The urge will eventually come back. Just don’t try to force it because that will lead to burnout.
This happened to me with WotlK Classic. Leveled 1-70 in the prepatch, but then on launch night I just wasn’t feeling it and barely played.
In my case, the thing that motivated me was: I had a class that I really wanted to play (Holy Paladin) and I wanted to experience all my “first times” (dungeons, raids) while the world was still busy/populated (cause it’s pretty dead now until Phase 2 starts). That and I had nothing better to do at the time…
This motivates me in retail too. I’m eager to see how my fav class(es) feel this expansion with all the new stuff, and want to do the raid with my guild.
Okay, here’s your motivation. You’re lost, you’re angry in the woods, and no one is here to help you. There’s a witch, and she keeps leaving sh*t outside your door. There’s no one here to help you! She left little trinkets, you took one of them, she ran after us. There’s no one here to help you! We walked for 15 hours today, we ended up in the same place! There’s no one here to help you, that’s your motivation! That’s your motivation!
If you’re burned out, stop. You know how WoW catch up is by its very nature, you honestly won’t miss much if you chill to go play Valheim (fantastic game btw).
