Given that I have a full time job (for which I WFH) and run my own business at the same time, it's not so bad; that's 8 hours of the working day where I need to be at my desk anyway, and during weekends I tend not to be in there anywhere near as much. I do a lot of computer-based personal stuff too, which I really enjoy.
That said, yes - I'd rather be not working and sitting by the pool.
