The biggest change was how much more free time I had. When you're building a Nights and Weekends side project, you get used to stealing whatever free hours you can to work on the product. But you also necessarily build things so that they don't take up much of your time every day. If they did, it would interfere with your day job and that just wouldn't work. So when you remove the day job, you find that suddenly you have this successful business that runs itself in the background and you can do pretty much whatever you want with your day. Most people in this situation will immediately fill that time up with work on the product, and I did to some extent. But I also made sure to take a bunch of that time just to enjoy with my family. I eventually settled on 2-3 days a week where I was "at work", with the rest devoted to other pursuits. Both me and my wife are rock climbers, which is an "other pursuit" that will happily expand to fill the time available. We're also parents, so ditto there. I also make a point of downing tools for a while from time to time. Again, because I can. I took the kids out of school and dragged them off backpacking around SouthEast Asia for a few months the first year. We did a couple more medium sized trips this year, and I took the entire Fall and Spring off because those are the best times for Bouldering in the forest here. Again, work is happy to ramp up or down to accommodate because I never shifted it out of that ability to run on nights and weekends. So now, I burst for a few weeks at a time on work stuff (with possibly a more relaxed definition of Full Time than most would use), then slow down and relax for a bit. It's actually not so bad.
