I didn't feel the user interface was ready. Also, as the system is a database at heart it has to be absolutely rock solid.
Planning to launch on the 5th of Feb, which is the date (4 years) since I wrecked my knee and started working on this project to keep my mind busy. See https://velox.io
Launched earlier this year with a $500 budget, now making ~1.2k revenue per month trying to grow it further. Still need to get a job though, $200/mo is not much fun for food in Seattle.
Too many hours devoted to employer. I already have something bootstrapped active (movinggauteng.co.za), but stagnating a bit. Wanted to launch a small December idea to take my mind off my 2 jobs. This year I'm aiming to work no more than 48 hours a week for employer, start making money on bootstrapped product, and enjoy my life more.
I didn't launch sooner as I was focused on too many projects. Finally buckled it down and drove my project to completion. Official launch will occur in a week or two: http://rallycoding.com/
Nothing! Launched and now have profit! Going Lean and doing customer dev before product dev was a huge factor for success.
Nothing, I launched, but I need to refine it and make it look better: bestfoodnearme.com
Concern about if what I built was too specific to me and if others would even use it.
Nothing. It launched. Then the co-founder quit and took it down.
It's coming back soon though.
I have no idea what to build.
I was consumed with a product I launched in 2014 :)
I was too lazy / busy to finish it.
Launch.
Nothing stopped me, I was trying to build it out. 2016 will be my year to get beta users and really get things going. You can check it out at http://localhost:3000 ;)
Took over a year to find the right direction and didn't start building the product until the end of August. This stuff takes a lot of time. When I was young I never understood the unhygienic programmer stereotype. Now I have become its embodiment.
Stop looking for productivity 'techniques' that others have found to work for them and just do the best thing I can think of now to get something done.
Momentum tends to work better than any one 'technique'.
