Yet another strategy is to go work on other people's projects. Go find something close to what you built (or several) and see how their code is organized. Spend some time with it, change things, add a feature you want.

I have lots of todos of various sizes on my project if you are interested, and one of the goals is to explore, capture, and reuse software patterns much more easily
