I've started a handful of side projects over the years, usually trying to fill a niche for small businesses, but none really took off because I grew uninterested. Once I started a project that was a) related to a hobby I already had and b) something I actually needed to use in real life, building it became a hobby in itself, I looked forward to working on it every night before bed, and eventually shipped a real product.
