Just talked with a busy mother talking about her life: "My day is packed, 6am to 7pm. I mean packed. I’m using minutes I didn’t even know existed. Those ten minutes I would use to sit at my kitchen table before going to work? I used them to make the sauce for tonight’s dinner."
On the one hand, I can’t imagine being a parent. It sounds like the work schedule of an entrepreneur, except your customers are whiny inarticulate blubber balls, and your opportunities for drunken debauchery diminish considerably.
Two, there is so much more time in the day than we realize, or often have the know-how to utilize. Efficiency is as much a matter of skill as of willpower.
