I find it helpful to make lists for myself. Checking things off of a list always feels like progress, which itself is a motivator. To take a real life example- when I was doing iPhone apps, I noticed that a common pattern for me was to lose interest/motivation when all of the ugly details began to emerge from what initially seemed like a simple weekend project. My way of dealing with this was to always keep a prioritized list of the absolute minimum features I needed in order to ship it. It's always easy to get a little off-track while investigating ideas, so I tried to focus on what the absolute most important aspects were. You can always work on a 2.0 after you ship 1.0, so try to focus on the most important aspects without getting side-tracked by non-essentials.
