"Twin studies and other research have shown that about half of the variation between individuals results from their genetic inheritance and half from their environment. Researchers have found conscientiousness, extraversion, openness to experience, and neuroticism to be relatively stable from middle age through old age" [1]
What if you don't feel any curiousness? Or you feel it for something that is counterproductive at the moment?
What if your desire of making something great clashes with your boss order to make some more boring CRUD software because that's what the client wants?
In these cases, anxiety and inadequacy could be the very emotions that recenter you on what you should to do.

As far as emotions like inadequacy and anxiety, I think mindfulness is a useful tool in terms of differentiating between having those emotions and dwelling in them.
For instance, recognizing one's sense of inadequacy, and from a sober state of mind being able to decide whether that is a signal to reenforce one's skills in some area, or to remind oneself why that reaction is inappropriate in this case is a healthy response. Just walking around feeling bad all day due to imposter syndrome is not a healthy response.
At the same time, it doesn't have to mean that one cannot improve things independently. We can't change personality, but we can change beliefs, which also affects what we feel.
Consider this: I used to feel really bad about having my pull requests getting reviewed, because other programmers would leave insensitive comments full of criticism. At one point, I just realized that they are not motivated by shaming me, but that they just care about the codebase's quality (and are not very good at conveying emotions in written comments). This change in perception literally changed how I feel about it.
