WATCH: Judah Tyreman, curator and manager at Sesula Mineral and Gem Museum in Radisson, Sask., has published his second financial aid book, "The Richest Kid in Babylon," at just 16-years-old.

Ramit Sethi’s personal finance book is designed to appeal to people in their 20s and 30s. It’s funny and tongue-in-cheek, yet very practical, which is the best part.
