1) Firstly, that you were in business to add value to customers and that was the primary motivation. It seems your primary motivation was to learn/experience it. Which is fine - it's just not what I assumed it was.
As Zig Ziglar would put it - To get everything you desire in life you just have to give enough other people what they want from life.
* Who knows what approach works better. For me, the Zig Ziglar approach has worked much better but that's a sample size of 1 person.
2) Secondly, my mistake in assuming your post was meant to help other people. If you could have added a note that it was meant mostly as a catharsis and written for yourself.
Then I wouldn't have assumed that there might be a lot of value for me.
Right now the value is in seeing a few things but the amount of effort is just not enough to actually know whether any of your mistakes other than not putting in enough work matter.

See, the key thing is your line on work being from 0 to 10 hours per week with some weeks being over 10 weeks.
How can you know your ideas and business were right or wrong with that amount of time?
For entirely selfish reasons (to help myself) I wanted to learn from your experience. However, if your experience is based on working an average of 10 hours a week, then it doesn't really say anything about what the market opportunity really is/was.

On a related note there seems to be a fascination on hacker news lately on apps done in 5 days and 'passive income' and how to succeed without working hard.
Are there any people there who are succeeding after working really hard? Who are spending 5 months on their app and not 5 days?
