That is absolutely one of my favorite books. I had it years ago and can still literally quote from it.
One of the parts I like best is where her father goes out and fishes everyday and incurs the ire of the old codgers who think he doesn't "deserve" to be out there. They do because they worked all those years and EARNED it. So he comforts them by pointing out that when he's old, he'll probably be up a creek without a paddle, and they go off, mollified, and he just keeps on fishing.
We "dropped out" of the regular working world at 42 and 50, fifteen years ago, and I can't tell you how many times we've been in that position. The joke is that because of our frugal ways, and because in those younger years, we tended to reinvest our dividends and keep our lifestyle together by sporadic parttime jobs, we lived as free as Dolly's father, and STILL managed to find ourselves up a creek with a very big paddle. I always like to think about what those old codgers would think of that!

P.S. That darned book goes for more than $25 on Amazon.com most of the time at present. So any who have it and are willing to part with it, that's money sitting there on the shelf. Not to mention that it could be out there in the world influencing yet another person......
