I know how to fly a plane. I have even sat in the jump seat of a 747 and observed every step the pilot made to safely land the beast.
Despite this wealth of knowledge I suspect neither of us would be comfortable with me taking the controls of our next flight.
Turns out that no matter how knowledgeable you are, without a measure of practical hands on experience you're less than halfway to being an expert.
Mastering a skill comes in two parts: knowledge and experience.
You might have watched—and even memorized—the content of 100 HiFi room setup videos, but until you spend the time successfully doing the work you're only at the starting line.
Which is fine. My only point is to gently remind those of us sitting in judgment of others who have successfully made it through the experience mill, that it's easy to criticize but harder to appreciate the value of the work.
