Every article about remote work makes it sound harder than it really is, and probably scares a lot of people off. I've been doing it for 3 years now and don't suffer from these problems. There was some initial shock for the first month or so where home = work = home but once I got past that it became easy. Now I wake up, grab my laptop and sit on the couch and work. When someone wants to talk I go to my office, or if I need heads-down time.
Otherwise I just live my life. I usually sign off around 5 and take my dog for a walk. I do normal hour-ish long lunches. If I need to mow the grass I go do that, no big deal.
