It's really tough (impossible) to think/work/act your way out of being burnt out. You need to reset, recharge, and then rebuild.

And from the very limited information here - you sound burnt out.

I don't know of many more longer term solutions aside from taking time out (and a lot of it, probably a vast amount more than people estimate). Obviously there is the exercise, sleep, floss, friends, family, pets, etc, etc. And I'd recommend that deeply. But that can be hard to effectively build without the battery having a decent amount of charge.

Not everyone can just peace out for a month, or 6, or a year. It's an enormous privilege to be able to do so. But take what you can.

Best of luck.
