Truth be told, Derech HaMelech and others, some ma’amorei Chazal to consider:
“Chasid-shote is one of the mavlei(one who wears down, destroys) olam”;
“Any Talmid Chacham who has no deya, a piece of neviela is better than him”;
“Hamegale panim be’torah shelo ke’Halocha has no helek le’Olam HaBa” (something some too-Yeshivish people engage in — by trying to turn chumros into hiyuvim).
