And, yes Charlie I agree with you that hard work and planning pay out in the end, and I also agree with you that it is possible to fake inspiration. I believe that this is exactly what this great singers do. They are actors, They try to be the boy who lost the girl he loves, or the cowboy on the plains, or the boy in the Getow or whatewer. Or A country star singing in front of an audience.
They use all the mental trix they have to be in a mood to communicate the song to the best of their capabilities.(WITHOUT OVERDOING IT.)
