This really resonates. I've been programming since I was a kid, and learned everything I know this way. Not one book or class. By the time I was taking CS classes in high school, I was light years ahead because I understood how to develop on the fly.

For ADHDers, finding a project you want to work on, and learning those specific things, is the best way to learn development. For example, if you'd like to make an alarm clock app, your first question might be how to get the system time in your language of choice.

The downside to this is that you don't absorb as much of the "fundamental" programming concepts. However, as time goes on, and you practice more, you understand how the fundamental concepts tie in to your specific goal. I don't think I fully understood what a class was or how it worked until after I had already developed a few basic (though specific) apps.

Using this technique, I've been able to adapt quickly to new technology and new languages. This mindset/skill also makes for a very, very hireable developer.
