Keeps me busy and up-to-date, and is extremely gratifying.
I'm getting ready to release an app that is a top-to-bottom system, involving a couple of servers that I wrote, along with a fairly robust native iOS frontend.
Works a charm. I've enjoyed it. Of course, I have to keep my scope humble, but I've always been able to punch above my weight, so it's working out.
I've found that most non-tech folks don't have any idea how much it costs to have real talent working for them (or even crap talent). I don't feel like arguing about it. I can't declare it, so it's not worth the agita.
If I was able to declare it, I'd never pay a dime in taxes.
I have heard that Steve Kamen, who wrote the "I Love New York" jingle, gave full rights to the state, and never has to pay state taxes. I haven't found anything that corroborates this, but it could very well be true.
The work I do, is for a demographic that tends to be ignored. I doubt there's any tax breaks, headed my way.
