Being very insecure, I love it when other people tell me I'm not a screwup. For example, Apple just put my Molecules app in their latest TV Commercial, indicating that at least someone likes it. Granted, you can only see it for about half a second in a couple of places, but I'll take what I can get. It's also listed in the website about the commercial, so people have a way to find it.
And Molecules was also just listed in Apple's "Best of 2014" for iPad apps. It's not the best iPad app (that's some other dumb app) it's just one of the short list of not-quite-as-best best apps. That's pretty nice considering how many contenders there are, and even nicer when you add that three other Touchpress apps were also on the almost-best list: Beethoven's 9th, Incredible Numbers, and Vivaldi's Four Seasons.
Shrinks call this external validation, and you're not supposed to rely on it for a sense of well-being. But it doesn't hurt.
