I appreciate ideas that provoke self-reflection, but I wouldn't necessarily limit learning to a specific list of rules. Its useful to realize guides tend to embed value judgments. Recognizing and learning to step outside them teaches us a lot about ourselves.
In general, since we're always changing, it pays to be willing to accept some things defy what the person we used to be would've assumed to be logical.
"The trouble with most people is that they think with their hopes or fears or wishes rather than with their minds." ~Will Durant
