In this sense - continuously be building things. Repetition and practice are what lead to progress and mastery. However, it is not a plateau - progress requires slow growth.
I think this is the biggest thing beginners try to avoid. Especially if they're ambitious and want to be capable now.
I'm currently at the theory of becoming capable is a mixture of study, practice, and hacks. You study the things necessary, then you practice them producing results to evaluate, and then you find hacks that amplify your efforts. But, I have zero research to back this and it's just what I try to do.
