I've created dozens, and dozens of side projects over the years. The motivating factor for starting any of them, is the interest in learning a new technology. I then use what I've learned from that side project, to build upon another one, and so forth. Cumulatively, they strengthen any "real" projects that I've had interest in building. Piece by piece, I build knowledge on various aspects of what my ultimate goal is.
