Sure, if your aim is to build something for fun or learning or your portfolio, those are valid goals.

The OP however considered their effort a failure, because they aimed at making something that would be a successful business venture (they are not clear about this, but one can read between the lines).

Fair point. Though in my case it is also a business venture, but with very modest goals and building it consistently because I want it to exist

I guess my point is I just hope the author wasn't too quick to write off their attempt as a failure. Things can succeed after their first year, or even after their fifth
