You use your experience, knowledge and ability to make decisions—that’s judgment.
Looking at yourself or others with a critical eye is also judgment.
You can use judgment (the former) to make decisions.
The other judgment (the latter) is a waste of time and detracts from living a happy life.
As you move towards or through Chapter X, hold the first dear and reject the second.
Use your wisdom to live your best life while trying to avoid applying criticism to others for how they spend their money, live, what they wear, the music they prefer or their politics (the list is countless).
