I've worked from home for 22 years, I go to the office in Basingstoke 1 or 2 days a week, I run the company with another director.
Like Andy I can be up early and also working late as most of our business is international. When I'm working I'm very much working so Diane often complains she doesn't see me much even though I'm in the same house!
I quickly found that if working at home all the time it gets depressing, problems seem worse, there is no banter, phone calls and video calls help but there is nothing like going into the office regularly. If I lived near the office I would work there almost all the time but as it stands it's 1 hour each way so that 2 hours less work done a day.
Some people are unsuited to home working, they get distracted too easily.
