I would agree if night photography is all that is of interest. Getting proper exposure takes into account so many different aspects dependent on lighting conditions at the time thus understanding what occurs is critically important. If the OP can't learn by reading then watching videos or hands on practice is a good place to start. I still support getting published articles / books that guide a photographer in his / her area of interest. I'm generally a hands on learner but have purchased published material that have helped as a reference when needed. Bryon Peterson's book is by far the best reference I have to date (YMMV). Perhaps you are way beyond that and 100% capable 100% of the time. If so perhaps you could memorialize your vast knowledge via video or written materials and share with others.

Actually, Dave, I work one on one with fellow photographers, and I adapt the delivery method to the individual's learning style. Books are ok, but often don't present the entire story in a factual manner - it is more about the way the author sees things.
In particular Bryan Peterson says things that I take issue with like the following:
"I know of no other way to consistently make correct exposures than to learn how to shoot manually." A newbie may be mislead into believing that the camera can make a mistake, if set to do determine exposure automatically. The only mistake is in not understanding what the camera is telling you base on what it is reading. So here is the first example of his approach, or opinion, being strongly presented as the best way to go.
In his chapter on Aperture, nowhere does he mention the impact on image sharpness of using tiny apertures, like F16 and F22, which will take any modern, high megapixel camera and have it produce images that have all the sharpness of a drugstore disposable film camera, though it will have great depth of field for "storytelling." He even describes in an anecdote how setting the lens to F22 and pressing the shutter release "the [automatic] lens would stop down to F22, transforming the fuzziness to sharpness" of a distant landscape with strong foreground and background elements.
In fact he routinely advocates using F16, F22 and F32 to achieve depth of field or F2.8 to achieve focus isolation - and suggests that F8 and F11 are "middle of the road" apertures that "rarely tell a story." You can see how someone who is new to this can misconstrue such a statement, basically an opinion, as gospel.
His treatment of aperture and depth of field is incomplete. He does not discuss the relationship between focal length, subject distance (image magnification) and aperture - another "trinity."
In similar fashion, he fails to describe the relationship between shutter speed, distance (magnification again), and freezing (or blurring) motion - yet another trinity. if your subject is moving and you are at 200 ft distance you do not need as fast a shutter speed as if you were 50 ft away, with the subject moving at the same speed.
I can go on but I think you get the picture.
I am not condemning the book. It is a very useful reference with lots of good information. But it does have a fair amount of opinion presented as fact, that can steer someone in the wrong direction.
This book was written in 2004, and some of the info is dated. DSLRs were only available with cropped sensors, and the term digital camera generally applied to what we refer to as point and shoot or bridge cameras. I have not seen the 3rd edition, which was published in 2010, so my comments are based on the original edition.
A more complete practical understanding of exposure can be achieved by reading the Zone VI workshop by Fred Picker, The Negative by Ansel Adams, adn The Practical Zone System by Chris Johnson. Unlike Peterson's book which is all about how, these books also cover the why. There are others, but these are the ones that come to mind.
