Bingo. Working from home also exacerbates this, since there is no longer a physical division between "work" and "home", plus there is virtually no social pressure not to slack off.
I think that works both ways. If you want to work more, it is easier to do from home as there is less social (i.e. family) pressure to come home from the office. The key is to find a workable balance.
Well, it pays off to be aware of the issue at least, right?
I too have grappled with this for a while but I believe this struggle was for the better and it eventually led to reduced stress. Nowadays when I mentally proclaim "I am done for the day!" I know that I did my best and that I have put enough hours / effort to not feel guilty about not putting more.
So yeah, you are right. I just think people should go through this fight for discipline because it's ultimately better for their mental health when they learn to put boundaries.
