Relationships are generative, as in: people will unearth certain traits or ideas that you might not even consciously know that you contain. Some minds are extremely generative when they come into contact with yours. Spending time with them unlocks emergent properties. E.g., In a good conversation, upon being asked good questions, you can go farther/deeper into an idea than simply ruminating alone. Same thing applies with a good partner or good friends, your journeys are enriched by each other’s directional force.
