I have an overall vision for something that I want to make. A rough outline so to speak. I then start to chunk it up into mini-projects. And, sometimes chunk those down into even smaller collections of tasks. I pick one of those mini-projects and start building it. I often use paper notebooks and pencil to sketch screen shots, diagram logic flows, create data schemes and more. Then I make lists of things I need to build. As I get into the details of building the mini-project my thinking clarifies and that gets codified. I just keep trying to build the next mini-project and connect them together and after awhile the project is "done."
