I got to a point in my career when I realized that I can, and will, be replaced, and the work will continue. It made me feel less personally responsible for my work (i.e. "no one can do it except me!"). Once I reached that point, I was far less invested and I suppose that I kind of quiet quit, but really, I just adopted a healthier perspective. I remain perfectly willing to help other employees and be a team player that will work extra when required, but if it can wait, I'll see you on Monday.
