Her story is actually interesting, but the conclusion of the post (and the title's question) is "I gave up extreme minimalism so I could keep things and go back to them from time to time."
I mean this isn't exactly profound.
Paraphrasing: "I bought a book to study German. Normally I'd throw it away when I'd get bored of it. Instead I'm going to keep the book, so if I have the desire to study German again later I can just pick it back up rather than buy a new one."
