The beginner's mindset.
The beginner's mindset begets curiosity. It enables learning. It weakens the symptoms of the imposter syndrome.
It says, "I am not an expert, I am trying to learn. I am merely doing a job. "
The expert mindset takes us towards the other extreme. It creates pseudo-confidence. It makes us seek reassurance all the time.
The best experts are those who are always looking to learn.
