Done this exercise before, but it's always useful!
168 hours in a week.
56 hours of sleeping. 112 hours left.
40 hours of working. 72 hours left.
21 hours eating/prepping food/pooping/showering/commuting/etc. (this is a bit of a slush area, you can make it more efficient) 51 hours left.
15 hours UA time. 36 hours left.
15 hours family time. 21 hours left.
That's twenty-one hours for EVERYTHING else if you work outside the home. Ten of those spent working means I have about eleven hours a week to do "everything else"; that includes chores around the house among other things. To make it work, part of what I sacrifice is in that twenty-one hours of "stuff". I don't tend to take lunch breaks (I just snack then eat a full meal with the family when I get home). The only meal I typically help prepare is breakfast and family dinner on Sunday. My chore load is lighter than the rest of the family, though I still try to spend about an hour a day working on various projects or cleaning around the house.
Did your lack of �me time� ever start to seem like sacrifice?
Not particularly. What I end up sacrificing mostly is stuff from the 21 hours of slush area, and most of it I don't really miss. My commute is short or non-existent depending on the day. I cook breakfasts with my wife and a meal on Sunday; my wife & kids take care of the rest. I don't linger in the shower or take very long with my morning constitutional
My coffee is instant, and "projects" around the house go un-finished for a very long time unless someone else volunteers to help so it becomes family time. I don't personally require 8 hours of sleep; if I get more than 7 in a night, I start waking up for an hour around 2AM pretty regularly. That's about it, really.
