On this week’s episode of The Happen To Your Career Podcast, four-time NYT bestselling author Gretchen Rubin dives into the science behind unmet resolutions, the anchor holding you back from your side gig, and the reason one “right way” might be...well...bullshit. A seasoned podcaster, she regularly co-hosts the Happier Podcast where she provides tips for making and breaking habits and success strategies for each personality type.

In her latest book, The Four Tendencies, Gretchen explains a personality framework involving, as you would guess, four tendencies. Each identified type is characterized by their tendency to respond to inner expectations and outer expectations. (Inner expectations being those you set on yourself—like New Year’s resolutions; outer expectations being those put on you by friends, coworkers, family, etc.)
