Do you have a hard time letting go of your work? When? What do you do about it?

To be clear, I’m asking for others’ experiences, not seeking advice. This isn’t a big problem for me.

I’ve learned I shouldn’t do homework, especially math, right before bed. My brain continues to work on any nagging unfinished problem while I sleep, and let me tell you, sleep in which your brain is trying to do math is the least restful sleep out there.

Does your work push its way into what should be your personal time?
