I agree, however in my case the motivation was to build something I myself want to use. It's been a long road to build it but I have found a small handful of organic users (almost entirely from Show HN post I did last Dec), who've said they really like it and continue to show up. However the dev process has been so long that I've frequently become disillusioned.

But sometimes you will never know unless you try.
