The usual diagnosis for tutorial hell is that you're not disciplined enough. I think that's backwards. People stuck in tutorial hell are some of the most motivated learners around — they keep starting. The problem isn't willpower. It's that there's nowhere for what they learn to land.
Tutorials are input. They pour knowledge in, but if you have no project to attach it to and no order to put it in, it evaporates. You finish the video feeling productive and remember almost none of it a week later. That's not a you problem; it's a storage problem.
What actually works is reversing the order. Pick a destination first — something you want to build or ship — and pull resources toward it as the project demands them. Learn the next thing only when your project needs it. Just-in-time, not just-in-case.
Concretely: one project, one running notes doc, and a rule that you only open a new tutorial when you hit a wall the project put in front of you. The tab-hoarding instinct is fine — squirrels hoard too. The trick is burying nuts you'll actually dig up.
