It also occurs to me that while 'bad' teachers can often still hang on to their jobs (I've had more than my fair share), very few bad entrepreneurs can still hang on to a business!
I guess the point I was trying to make was that some people are very good at teaching (or blogging) even though they may not have necessarily done what they teach about. For example, I've had great teachers - politics teachers, English teachers, professors in law school, etc - who didn't practice what they taught i.e. my high school politics teacher wasn't a politician, my university film studies professor didn't make movies, my law school professors were not practicing lawyers or judges (in fact my contract law professor was brilliant yet had only practised law for a year before turning to academia), etc. So it is conceivable that someone could teach or communicate something of value without having the personal experience of practising the profession they're teaching about.
Having said all that, when it comes to someone making grand statements about what constitute the keys to success, etc this may not be something that you can truly and credibly teach purely based on persoaln observations or academic study (as would seem to be possible regarding subjects such as politics, film and law to repeat the examples given above).
This seems more like someone attempting to teach or make statements about what it takes to successfully climb a mountain. Mountain climbing is one of those subjects - to which I would definitely add building a business - that can't really be taught by someone without personal experience. These are subjects where the 'lab' is the real world, so unless someone has been in the real world, they really don't have helpful lessons to offer.
