My advice: It’s probably not that you’ve lost interest in your project — it’s more likely that you don’t know what to do next and you’re defaulting to your comfort zone: building the product.

Here’s an easy way to test this: imagine your product suddenly takes off — it gets picked up on Reddit or Hacker News, you start getting lots of users and feedback. Would you still feel uninterested? Or would you find yourself energized, working late into the night to improve it?

That thought experiment reveals something important: there’s a gap between building a product and getting people to use it. You haven’t figured out how to bridge that gap yet, so you stay in “builder mode” — because it feels safe and familiar.
