A practical guide to money management and how to reduce spending. - Title: How to Reduce Spending - Author: Hiroshi Mori - ISBN: 978-4815042233 - Publisher: SB Creative - Language: Japanese Thank you for viewing. I read it once and kept it at home, so there are no stains or scratches, but it's not quite new. I read it because it was a book recommended by Ryogakucho. It's not that the more money you have, the better it is to spend it. I thought it was a waste to have money that doesn't move, though (lol). I am also listing it on Rakuma, so please forgive me if the timing overlaps.
