...and how much do you consider to be sufficient?

As a card-carrying member of the sandwich generation, I've been struggling with this. It's one thing being busy if there is a light at the end of the tunnel. I'm OK with that. In fact I've been living my life like that lately: just get through this week, this month, this semester, and you will get a break. And there always IS a break, but it's always too short!

So when your life is "normal" -- i.e. you're not in a crunch period -- what amount of free time per day would you consider acceptable? An hour? Two hours? Five hours?

I guess I'm just looking for women -- especially older women -- to say that it gets...not easier, necessarily, but less frantic. I've talked to a few women who felt like their 40s were their busiest years, and that it got calmer after that. These are professional women, not lifelong homemakers, btw.

And I'm speaking from a place of privilege, I know. I'm not getting up at 5 am every day for backbreaking manual labour, and for this I am profoundly grateful. I am a middle-class white woman who had the good fortune to be able to stay home with her kids when they were small, and I continue to have the good fortune to pursue further education now that they're older. I'm not wishing for a different life. I guess I just want to be reassured that there is indeed a light at the end of that tunnel -- where life will settle down into a comfortable "busy-ness", as opposed to the frenetic kind.

Any thoughts from those who have been there?
