One can read a lot of calories and do a lot of exercise. But unless you understand the fundamental principle of progressive overload, weight training will never make sense. Is there an equivalent principle in TRP ?

My guess would be AWALT or some other facts mentioned in the red pill antibiotic nuke. But most of these are Truths about the world around and not really concepts that can help us after we accept the red pill. Another set of principles is probably the dark triad, but they're I believe quite complex and can't be treated as a single fundamental idea to move forward.
