That's that threshold between competence and mastery. Most things are pretty easy to pick up and get consistent feedback in that the amount you learn and effort you put in you get back out until you hit a wall where you perfect all those techniques which is the truly difficult part.

Probably the most famous example is writers block. By then you probably have all the techniques down and they can create good work, but plugging them in doesn't automatically give you the level of mastery you hope for.
