“Conscientiousness

Not every anxious person is conscientious, but because you’re reading a CBT-based self-help book, there’s a good chance you’re at least moderately high in conscientiousness—a personality trait associated with having a strong work ethic and a thorough, orderly approach to tasks. People high in conscientiousness often get particularly great results from learning cognitive behavioral principles and skills. Why? They tend to like the systematic nature of a cognitive behavioral approach. They do well because they work hard to understand themselves and are diligent in applying their learning to their lives. Anxious people sometimes underestimate how conscientious they are, so make sure you give yourself enough credit for your conscientiousness.
It’s important to understand that conscientiousness is not the same thing as perfectionism. For example, perfectionists might spend so long trying to make something “just right” that they don’t have any willpower left over for other important tasks. Perfectionism and conscientiousness tend to be associated with opposite outcomes. For example, in a study of older adults, perfectionism was associated with an increased risk or mortality. Conscientiousness was associated with a decreased risk. There are big advantages to reducing perfectionism but retaining your conscientiousness!”
