But make sure to leave room for your blood, that’s pretty important too!
This is obviously a different wording of “In order to love someone, you must first love yourself.”
I get it, I do, but I don’t like replacing the word love with heart. Because if heart = love, then people with “heart problems” or a “bad heart” then transitively have “love problems” or “bad love,” which is unfair, because people with medical problems have it hard enough.
