english: Mark Twain says that proper preparation, or teaching, is so powerful that it can turn bad morals to good, it can turn awful practices into powerful ones, it can change men and transform them into angels.
non_english: On kaže da je dobra priprema, ili podučavanje, toliko snažno da loš karakter preobrati u dobar, lošu praksu u moćnu, da promeni ljude i transformiše ih u anđele.
