Really? How old are you, then? How long have you run your own business? This year is my 41st as a professional in this field, and my 25th running my own business. I've written two books.
I'm not a lawyer, but I have been involved in 10 court cases as an expert witness, so I am aware of what it means to launch and win a lawsuit.
How many times have you been sued for defamation? Are you speaking from experience?
Technically, I am a CEO, yes. I accept that I do sound arrogant to you, since ANYONE sounds arrogant if he is confident in his hard-earned knowledge of how to run a business and is being heard by... who? some random kid on the internet who lacks the self-awareness to realize that he arrogantly and ignorantly dismissed someone else's experience without having any particular relevant experience of his own.
