She also adds that to say that it's unexciting is not to say that it's easy. For me, however, it was easy. I grew up with so little that it was not hard to save once I started earning what I regarded as a high income. I was never tempted to go through catalogues (remember those?), picking out things that I wanted and ordering them. Instead, I would do what I did as a youngster: go through catalogues, see things I wanted and fantasize about them, and then not buy them.
The only thing I would have added is that it's a way to get rich slowly.
