well family can fit into belonging, for me that's how I took it. not sure where else I belong but with my family. the others where purpose, transcendence which she described as feeling connected to higher reality (so going to church to some, looking at art to others, being in nature to someone else, maybe meditating to another), and story telling which she described as the story we tell ourselves about ourselves. We can focus on the positive or the negative. Her talk wasn't about being happy or even content but finding meaning in our life, that that was a better and more fulfilling goal post.
