An entrepreneur is not what you call yourself, it's what someone calls you in recognition of what you've achieved. I call Richard Branson an entrepreneur. Rupert Murdoch called me one. Anybody who stands up and says: 'I'm an entrepreneur' needs shooting. You'll drive people crazy.
If you lock me in the room with a piano teacher for a year I might be able to knock out a rendition of 'Roll Out The Barrel,' but will I ever be a concert pianist? No.
