Your life is time. Your job consists of 40 hours plus if you are employed full-time. but, that’s not the entirety of the time that your job encompasses. Commuting, getting ready for work, being interrupted off hours my work, and simply thinking about work even when you’re not working at all adds to the amount of life that your job invades.
That horrible boss, stressful project, corporate façade, meaningless work activities, and generally mismatched career were strangely created, at least in part, by choice.
You accepted the job. I realize that there were likely a multitude of factors that made it seem like you “had” to take the job. But, in a literal sense, you chose your job.
Now, you should choose to move on if you want to change your life.
