Sometimes It’s Best to Express Your Wisdom in Silence

“An ultracrepidarian is someone who goes ‘beyond the shoe.’ He is ‘one who is presumptuous and offers advice or opinions beyond his sphere of knowledge.’ Or ‘someone who has no special knowledge of a subject but who expresses an opinion about it.’ Apelles’ concern was that the shoemaker should stick with his area of expertise and not presume to be an expert on everything.” - Challies
