I can't vote on this, because there isn't a right answer. The true conflict is the one with yourself. You have to make sure your story is exciting enough (not necessarily action-packed) that you're excited to return to it, otherwise you readers may not be, and they'll be all the more disappointed if you stop releasing. You shouldn't wait to release your finished products, because the momentum may be it's own self-fulfilling motivation, but you also shouldn't release things you're not excited about, because maybe there's a reason you're not excited for it that could be changed. You should have an outline/roadmap that serves as a complete story. After that, I'd suggest a workflow that chronologically accounts for concepts, concepts made into drafts, edited drafts, and then complete chapters. You should be confident and excited when it's time to release a chapter, and the workflow should never be entirely dry. The 1% effort you put into conceptualizing the next chapter should serve as an investment you already made and want to see through. For example, I have about 5 chapters of my main series released, 10 more in the backlog, and 4 after that in the concept phase. I'll take the next chapter from concept to draft, fiddle around with it until it's ready, and it'll join the backlog. It's way harder to procrastinate and get lazy when I already invested the time into the future.
Different workflows work best for different people, but the idea that you'll lose fixation is a self-fulfilling prophecy if you don't actively fight against it. Forgive me if I'm offering unwarranted advice. I just think the most common weakness amongst authors is procrastination, and the culture of authors patting each other on the back and laughing it off isn't very helpful. Yes, it's a thing that happens, but if you want to stand out in an incredibly competitive scene, procrastination is something to overcome, not expect. Everyone does procrastinate, but we're creatives. You can always procrastinate in a way that harnesses your craft. I usually watch 1 to 2 hours of something a day, but I'm always analyzing it through a writing lens. One show I'm watching right now gets under my skin with they way they introduce plot elements sporadically and hardly resolve them, sometimes bringing them back when it no longer matters. It's a note to self to not do that.
I believe in you! It's not about if you release or stack, it's about staying on task until completion regardless. As long as you're taking care of your mental and physical health first, then fingers to the keyboard should excite an aspiring author.
