The plateau has a name
You finish lesson thirty. You start lesson thirty-one because it feels safe. Meanwhile you cannot invent a small program without a narrator. That plateau means tutorials have done their job for now. The next teacher is a blank file and a goal you chose.
Signs you are ready: you understand variables, if/else, and loops well enough to explain them; you can fix simple errors without panic; you have passed a few labs. Signs you should stay in lessons a bit longer: you still cannot write a loop without copying; every syntax error ends the session. Be honest. Either way, pick a date to start a tiny project.
How to switch without drowning
Choose a project from How to Build Your First Project. Keep one tutorial open as a reference, not as a script. When you get stuck for fifteen minutes, read the relevant chapter, then return to your file. Do not open a new course. The course will still be there after you ship version one.
Alternate days if you need comfort: project day, lesson day. But the project day must produce a run of your program. Watching another introduction to variables does not count as project day.
Leave tutorials when practice feels easy and starting feels scary. Scary is the signal to build, not to binge.
