It's a mistake to prioritize romantic and familial relationships over friendship, argues psychologist Dr. Marisa Franco. Strong, supportive friendships expand our sense of self, she says, and are associated with greater well-being and health. Marisa offers research-based strategies to make new friends and deepen our existing friendships, including helpful concepts like mutuality and the mere-exposure effect. Marisa and Maya also discuss how to stay friends through big life changes, why fighting could make your friendship stronger, and how to break up with a friend with clarity and kindness.
