Earlier quoted context omitted.
The place you are looking for exists: it is called home :-)
That may fly if you are single. Otherwise everybody will assume that if you are at home, you are here to go shopping, take care of kids, let in guests, cook meals, do cleaning, take out trash, etc. ect, and lets not start about other household members distracting you with loud noises.
I also had to explain money to my kids. All that stuff they enjoy - we only have it because I can sit here and work. Once they understood there was a reason I wouldn't drop everything to play Mario Kart all day - life is good. That doesn't mean I can't take a break to have lunch with the family and take a break for a few laps of racin.
I find that it is easier to control the distractions at home than it is at work. People at work have work related things that they think are important, but aren't really. It is much harder to train them than it is my family.
