“Ne sutor ultra crepidam” is a Latin phrase that can be translated into English as “Let the cobbler not go beyond his shoe”. This proverb suggests that individuals should not offer opinions or advice on topics that fall outside their area of expertise or knowledge. In other words, it advises people to stick to what they know best and avoid giving expert opinions or judgments in fields in which they lack competence. This phrase highlights the importance of specialization and the need to respect one’s boundaries.
