It's not guilt that's the problem. Just because you're in a remote work situation doesn't mean you just stop thinking about the boring shit that you do. Meetings also don't stop. You get angrier and angrier about the whole situation. It nags on you and actually spend more time thinking about it than you would normally spend on it outside of work.

I guess there are quite a lot of people that can just tune out things they don't like, but I'd wager most people are not capable of that trait. I think the more competent you are the more it bothers you not to produce anything. And it's not related to guilt, at least it never was for me(and looking around in this thread I'm obviously not the only one).

Just because you are paid doesn't mean you want to pass your life without perspective. This is basically someone sucking your life away without drive or mission and only compensating in money. And if there is any truth to the "Drive!" book, then the money is almost secondary to the other two factors.
