I tend to make a quite strong distinction between 'work' mode and 'not work' mode. Certainly when working on your own business, there tends to be some gray areas. I also aim to set aside reasonably fixed time frames for work. So in 'work' mode, even if there's nothing to do right now (almost never in my case but well), I'm always doing business development, research, planning/building new features etc. When I'm not working on my business, I tend to study (unrelated) topics, read, travel or spend time with friends. But why not build an extra feature? Even if it's not requested, it can make your overall product better. Or work on increasing your conversion rate?
