This week, we respond to a letter from a listener who's been comparing herself to others and competing all her life: for fitness, intelligence, popularity, likes on Instagram, and even sobriety. Now, in her 40's, it's spilling over to her kids. So we uncover the phenomenon of crab mentality and how it plays out in our lives. How do we deal with this very human instinct to compare + compete? Is it always bad? Why do we do it, and is there any way to step off the hamster wheel?
