That was the point when the failure really hit me for the first time. I'm a very optimistic person, but for a few weeks there I was very unhappy. The company didn't end though. I let it linger via my nights and weekends for another year and half or so, while I essentially dwelled on the past.
Continuing to think about it and tinker with it was certainly preventing me from moving forward onto bigger and better things. It was essentially a complete waste of time.
I had trouble letting go. And then one day everything changed. It wasn't an explicit decision I can remember, but more of a shift in state of mind. If anything, the trigger may have been moving my server and losing some of the files such that I couldn't easily get the learnection code running again.
Knowing when you've failed is a lot harder than knowing when you've succeeded, but you need the former to get to the latter.
As I argued before, impatience may kill startups, but it also frees up the founders of those startups to move onto better opportunities.
