I'm not sure if most of you know... but I built one of my first apps, Iron HUD, several years ago actually.
I talk a lot about it now because after a recent and very huge update, it's one of my biggest income generators.
But for 4 years prior to the update... it was a considered an absolute failure. It didn't get that many downloads and it was barely making me $10 a month. Now after the update, it's generating close to $1K per month.
What's interesting to me is that there are so many things I have attempted in the past and gave up on because they were "failing", but I wonder how many of them were actually "eventual successes" like Iron HUD...
I just didn't have the stomach to wait.
