Working from home, versus corporate office life:

Discipline. Everyone talks about how much discipline you need to work at home. But how much discipline does it take to go to the same strange city office every day, for all the hours of daylight? To sit still for all the hours of the day, to accustom your body to temperatures you haven’t chosen, and gaze across wide dim expenses at faraway windows?  To listen to no music unless it’s on headphones, look at no pictures unless on a screen, smell nothing but the smell of office. That takes discipline too; just of a different kind.

Some great examples of what a home office can be.
