In my experience, money as a side-project motivator or measure of future side-project success is folly. Make your side projects for fun, find other motivating factors to finish, or don't finish, it's all good. If you make something and gain adoption, then you can consider monetization. But otherwise, I've found building an imaginary future income on your not-yet-built, not-primary-work software does not result in happiness or success. Granted, this is just my experience and only applies to side projects.
