It is often heard that most extremmely successful people suffer from Imposter's Syndrome". It is a natural reaction to the fear of disappointing the expectations of fans, followers, employees... When I was a musician I was sometimes nervous that I had not prepared enough, that I didn't know enough or just that I was not good enough.
The wonderful feeling about doing somenthing new at a later stage in my life is that I have no "Impostor's Syndrome"; I AM AN IMPOSTOR , and I love it.
So if you want to avoid suffering d¡from Impostor's Syndrome ... Change career and become an impostor
