The time argument is also weird. I find that I have a maximum of 6 hours highly productive work in me a day, perhaps an additional few hours of less productive work. A stroll or cooking recharges my mind. I envy all the people here who are working a productive 12 hour day.
in an urban area it makes less sense. Friend's house is across the street from a plaza consisting of a grocery store, corner store, starbucks, froyo joint, and a few other eateries.
Heck, when I became parent and decided for a couple of years to work at 80% I realized I was doing the same amount of work as before and as much or more than any other colleague working at 100%. I only came back at 100% because I realized businesses are willing to subsidize procrastination over efficiency and I didn't find normal to be paid less if all I was asked in return was spending 1/5 of my work time time doing nothing productive for the company.
