Just don't put too much of your heart and soul into your job. Don't believe in your employer's mission too much. Don't tie up your identity with your job too much. Don't work too many hours.

In other words have boundaries.

Have a life. Do stuff on the weekends and evenings. Hell, have a remote job? Do things in the middle of the day.

Do just enough at work to get a raise and not screw over your coworkers and no more.
