Not Matt, but I have a similar situation (3 kids, FT job, side project). My side project has been running for a few years now, but I am able to be pretty productive on it. First, I wake up early, and make sure the side project is the first thing I do every day. There's a book "the richest man in Babylon" and one of the ideas is "pay yourself first". I take that principle to my side project. I work on the side project first thing in the morning, to ensure I give it my best. I still want to learn and deliver good work at my FT job, but I've always ensured that from a time perspective I've paid into the side project first, because I believe thats the best long term career investment. Unfortunately, yes, this means that you need to set an alarm, but I enjoy the work, so I don't feel like I'm dragging myself out of bed. That leads me to my second point which is make sure you enjoy the side project. I've worked on multiple and the biggest mistake I've made is building something I didn't need or want. I built a few projects because they were technically interesting, not because I really needed them. For SAAS you might not necessarily directly need or enjoy the tool you build, but you better enjoy building it, and enabling others to use it! If not, it will be difficult to keep up motivation when things get tough. GL!
