Heartbreak Heals on Its Own; the Rest Takes Work
"They say time heals a broken heart" is one of those lines that sounds kind, but it hands your recovery over to the calendar. You wait, you heal, you return to roughly where you started.
Matthew Barnfield's argument in Psyche runs the other way: do the hard work of moving on, and you do more than heal — you improve yourself. The difference is worth noticing. Healing is restorative: it aims at the person you were before. Improvement is generative: it assumes the person who comes out the other side is not simply the one who went in.
The appealing part, and the slightly demanding part, is where that puts the agency. If heartbreak is something that happens to you and time is what fixes it, you are a passenger. If the effort of moving on is what does the work, then the messy middle — the part nobody enjoys — is where the change actually gets made. Whether that effort reliably produces a better person rather than just a busier one is the question the idea invites.
