Confusion isn’t a wall. It’s the loading bar before something clicks.

That muddled feeling is not evidence that you have reached your limit. It is what understanding feels like from the inside while it is still assembling. The discomfort is real, and it is also temporary in a way that panic makes hard to believe. Most people quit during it, which is the only reason it looks like a wall.

When the fog comes down, stay with the material ten minutes longer than feels reasonable. Write out what exactly you do not follow. Naming the confusion often starts to dissolve it, and if not, it hands you a precise question to ask.
