In all such middos, you only need books and lomdus if you want to skirt the line, such as (example from an old mussar sefer) “Q: the train ticket to my parent’s town is expensive, and halakha is that you don’t have to spend money on parents, am I exempt? A: yes, you don;t have to take the train, you should walk)
If you rather dress impeccably, be nice to everyone, don’t take OPM, you’ll rarely need a book to consult. I am not against learning about middos, of course, just saying lack of the books should not stop you from behaving properly.
