Curiosity mindset

Socrates once said that wonder is the beginning of wisdom. Today, many articles and books are written about curiosity and developing a curiosity mindset. In selling, genuine curiosity is also valued as one of the critical competencies to have. Overall, everybody agrees that it is almost a life hack.

Then, why are we still talking about it since Socrates keep coming back to the same point where we fail to apply it in all fields of life? Why could we not make any progress in using our curiosity to improve?
