Very good point, but I suggest you share it with Mike Mew as he is ultimately the one responsible for this mess. His message is spread out over so many videos and is constantly changing on some key topics. He also does not seem to be willing to address some key issues directly, answer Q&As frequently, nor provide a comprehensive guide for people to follow. It seems his main concern is just to make videos to catch more attention and steer up petty for himself.

I agree that in principle mewing is uncomplicated, but when someone has not been practicing proper tongue posture their whole life, and there is significant imbalances in the skeletal and muscular structures, than an uncomplicated process can become complicated. A lack of strength and coordination in the tongue and swallow muscles, narrow palates, asymmetrical jaws and faces, all can make mewing much more difficult. Yet even in these more complicated or difficult circumstances, the fix should be relatively simple following the simple guidelines you gave, but without a doubt, it is going to be a lot easier for some than others.

I do wish that Dr. Mew would create a concise 10 minute long video, addressing all of the lifestyle habits people should adopt. As well as address issues that people are having, specifically asymmetries and how to fix them. Initially I thought that tongue posture alone would fix them, but it now appears that it really takes I commitment to fixing structural imbalances throughout the entire body. People should know that going into the process of developing proper tongue posture.

Mewing is like learning how to walk after being stuck in a hospital bed for a few years. Youve never done it corrrectly so you dont know what way is the right way but as long you continue to walk you muscles will develop and your form will come naturally. So the most important thing you can do is make sure you only use your tongue every time you swallow. The cheesy swallow seems to accomplish that so in theory just do that consistently and you will get good swallow posture

Great analogy @Rockyp33

And to build on this when you start learning how to walk the hospital staff dont just give you few verbal tips like do this and that (mind you cluttered). They provide you a physiotherapy specialist for a couple months to help you learn everything. From there you start practicing it on your own for another year or two while under the physiotherapist supervision.

Now if your case is much simpler you might get away with one session and few occasional tips, but for most people that leads to no where but frustration.
