I think these things are important to have as tools in your life, regardless! Life can get overwhelming in all kinds of different ways; knowing how to put your head down and take care of yourself in these ways is incredibly valuable.

Unfortunately, after a while doing all the above and more, I realized my feelings towards my coworkers and company had nothing to do with burnout. Sometimes you realize everyone is miserably bad at their jobs and you don't want to keep dealing with an increasingly shitty work environment.

Another valuable thing is putting yourself in the position to be able to leave.
