Tutorial hell might be some type of procrastination. I'd watch YouTube videos all day on all topics because I didn't want to create something and just "learn", but it doesn't create real skill and it is not where the fun lies.

The biggest challenge might just be to find the thing you want and can do. If you really want to learn, then you might just regulate your want to some beginner level that is borderline useless.

Take language leaning for example, you want to speak enough to understand a conversation, but as this takes a LOT of time it gets frustrating really fast. What you can do is learn a simple sentence and try to speak it and understand it. "Good morning, how are you doing?" — "Guten Morgen, wie geht es dir?".

Or programing, don't think about this huge project, but a simple simple action; read variables from a document or create a function for some math. One of my first programing was calculating Fibonacci numbers.

In my opinion it might not be so bad to be stuck in tutorial hell, it might just be a form of entertainment for you. But if its a form of addiction, then maybe treat it as such. If it is a form of escaism then treat it as such. If it is adhd or autism or something else then treat it as such. Take simple and small steps, celebrate successes however small they are and think why you defaulted to tutorials instead of doing something, even thought you want to do something
