Gretchen Rubin and Chris Guillebeau

Gretchen Rubin, "The Four Tendencies" & Chris Guillebeau, "Side Hustle"

From The Happiness Project to Better than Before to her popular podcast, “Happier with Gretchen Rubin,” Rubin has probed the nature of happiness—what it is, what it isn’t, and how to have more of it. In her new book she demonstrates that this seemingly elusive state hinges on one key question: how do you respond to expectations? Rubin posed this question in an online personality quiz, looking at the expectations we encounter in a variety of everyday contexts. The results group people as Upholders, Questioners, Obligers, or Rebels, and once you know who you are, you can better understand your own motivations and make wiser decisions that lead to a more productive and happier life.

If you’re looking for a way to bring in more income, pursue a dream, or just see what it’s like to run your own business, you are probably thinking of a side hustle. A side hustle is defined as any entrepreneurial venture you can do alongside your usual day job, and Guillebeau, founder of the daily podcast Side Hustle School and author of books including The Happiness of Pursuit and Born for This, is a veteran of nearly a dozen side hustle enterprises. His new book is a step-by-step guide designed to take you from idea to income in less than a month.
