This is so relatable it's painful: many many hours of work, overly ambitious project, now feeling discouraged (but hopefully not willing to give up). It's some small consolation to me to know others have found themselves in this boat.

Maybe we were just 6 months too early to start?

Best of luck finishing it up. You can do it.

Thank! Yes I won't give up. The plan now is to focus on getting an income and try again in the future.
