It sounds like you're talking about project management. My approach is to keep the next 4 or 5 tasks to be done written down in a backlog. Writing detailed tasks about what you're planning can actually be quite fun once you get stuck into it.

Doing it this way means I'm wearing my project manager hat while I'm managing my tasks. So I can see the big picture, take in the wider context, and make more informed decisions about how much effort is reasonable to spend on each task. Whereas if I try to think about the big picture stuff when I'm deep in a rabbit hole with my developer hat on I tend to have a skewed perspective.

That being said, often the most difficult thing is staying motivated. So if you've enjoyed the process, and you've made something this beautiful, and no doubt honed your skills along the way, then I don't think you've got anything to worry about. Keep up the good work!

Also, what kind of print and media existed for thousands of years? I thought it was just religious scrolls and cave paintings
