In order to teach you must be able to do. Teaching (in my opinion) is the NOBLEST profession. Is there anything noble about being a critic and getting paid for it? When you see these various accolades about movies or books or performances or cars or whatevers how do you know they aren't saying what they are saying ONLY BECAUSE they are being PAID to give great reviews and being truthful has nothing to do with it? Are there honorable critics upon whom you can always rely to get THE TRUTH? Is being a critic like being a weatherman? You never have to be right about anything and you keep your job through all of it? Imagine never having to be right about anything and earn a living at it?
