Most of us are amateurs? Last time I checked (just now in fact) professional simply means you get paid for doing something. You can be terrible at your job but if you get paid for it you are by definition a professional! So I think this piece could have done with more care in terms. Additionally, it's pretty much just a list of assertions. Why should I give this any credence? On what basis was this list derived? It might all sound like good stuff but without any kind of decent context how is one to judge?
