I am crazy about the work of Gretchen Rubin, who describes herself as someone who researches happiness, good habits, and human nature. I guess that one of the things that I find most interesting about her is that she “started her career in law and was clerking for Supreme Court Justice Sandra Day O’Connor when she realized she wanted to be a writer.” Once she realized that, she just wrote. I haven’t read anything from her pre-Happiness Project period, and I may not have read any of her books straight through. What I recommend the most highly is her weekly podcast, Happier. I mean, when would you have another chance to listen in on the conversation between two sisters while one is cleaning the other’s closet! Her sister, Elizabeth, cohosts Happier and recently launched her own podcast, Happier in Hollywood. Elizabeth follows the cohosted model and does her show–which I also recommend highly–with her friend of 17 years and writing partner, Sarah Fain.
