I wondered about this myself, then decided I was overthinking it. So I made a basic separation: 50% goes towards learning, 50% to everything else. So whether I'm doodling or working on a project, any activity that isn't explicitely about learning technique, theory or soft skills goes into the other half.
I'm not great yet at enforcing this, but there is already more structure to my learning than I've had before. I figure it's best to throw as much time as you reasonably can to learning, because once you have success you'll struggle to find time to learn. And the 50/50 rule seems very reasonable, at least this early in my development.
