You can never have too many books on your reading list, and this suggestion might bring some variety to those you've already cracked open. Former reporter for Reuters and Newsday Lauren Weber just published her book In Cheap We Trust: The Story of a Misunderstood American Virtue, which focuses on the evolution of thrift, from the Puritans to the freegans. She keeps the text fresh by including personal anecdotes — she describes her economist father as "compulsively cheap" and admits that once he tried to ration toilet paper.
Lauren chatted with The New York Times about how she embraces the word cheap because living within her means has allowed her the freedom to never stay in a job that she didn't love. That's pretty powerful. The author is a pro at budget traveling and swears by public transportation and street food while she's on a trip.
I like that Lauren speaks from experience and keeps her topic from seeming stale by including her own stories. In Cheap We Trust is on my list as the next book to get me through my commute.
