What reading rules have you adopted or shed as you’ve got older?

Is there any received reading wisdom or rules that you’ve learned to shed as you’ve got older? For example: reading more/fast is better. It’s bad not to finish books. Etc

Or alternatively, any tongue-in-cheek rules that you’ve also adopted yourself to maximise your reading enjoyment?

One of mine is: if I want to read only the 5 star reviews in order to preserve the joy of a book I adored and skip any that don’t agree with me, then I will. Balance be damned 😁
