I already have the leanstartup and I have read many, many books on the subject, but I didn't do all this just to start a business. Of course, I want it to become successful, but this project means more to me than that, so I didn't need validation before starting on the journey. In a way, I was scratching my own itch. This is something I will use on a daily basis, and if that's as successful as it will ever be, then it was still worth it.
Seriously, I apologise if I make out in my post that this has been the worst time of my life! It wasn't the intention. For the most part it's been an amazing ride, and I had enough funds to be relatively comfortable while doing it (once I got used to the adjustments).
The advice to "scratch your own itch" is fine if you're building a hobby project. If you intend to build a real business then doing at least some "validation" (I hate how entrepreneurs use that word, but that's beside the point) is critical.
Even just talking to 10-20 people is better than nothing. Hindsight is 20/20, but hopefully anyone reading this reply takes a moment to do that before coding anything.
There's a lot of good reading out there around how to do what you've tried to do here in a safe and sensible way that doesn't waste time and your own hard earned money, but you seem to have ignored all of that. I suggest you purchase a copy of http://theleanstartup.com/
I genuinely wish you all the best of luck, but the way you've gone about this seems to me to be very, very foolish. Reckless even, given you have a family.
