"An expert is a man who has made all the mistakes which can be made, in a narrow field"

This quote by Niels Bohr recommends that true expertise originates from experience and gaining from mistakes. According to Bohr, a professional is not someone who has actually never ever failed, however rather somebody who has actually made all the possible mistakes in a specific location of knowledge. This indicates that in order to genuinely master a subject, one need to be willing to take threats and learn from their failures. It also highlights the importance of determination and constant learning in ending up being a specialist. In general, this quote stresses the value of mistakes and how they can ultimately lead to greater knowledge and know-how.
