Personally, I got to the point where I realized that trying hard to make software that's useful can turn a side-project into something stressful, essentially a second job on top of my regular full-time job, which I just can't do, too much risk of burnout. Trying to turn something into a side-business adds a lot of constraints. You're not just playing anymore, you have to optimize everything towards the goal of making profit. However, I still think you can enjoy working on things that are useful, to yourself and other people, and not for profit. The projects I'm the most proud of are projects I've shared that have been used and appreciated by many users online. You just have to keep the project small and simple, and keep your expectations low.
