As someone who is squarely outside the industry of "side project entrepreneurism," it sounds like the problem is obsessing over minor details about the project and never launching it.
The other person literally said they tried like 50 things and you two haven't launched any yet.
I put that in there to make it more or less obvious that perfectionism was one of the reasons I haven't accomplished much yet. The point was to probe deeper and see if there's some other insight, because everyone already knows that perfectionism kills productivity.
At the same time, if you're doing it for a hobby, taking your time until you're happy can be meditative. That's why I'm taking my side project slowly - because I enjoy coding and am using my side project as a form of relaxation.
