You get sharper by being around people who push back, not people who nod along.
Text the friend who tells you the truth. Ask them the question you've been avoiding.
This proverb comes from chapters 25–29, a section the Bible itself says was compiled by the officials of King Hezekiah from Solomon's sayings, some 250 years after Solomon. Chapter 27 has a cluster of sayings about real friendship — including the famous line that wounds from a friend can be trusted. The image is from the blacksmith's shop: one piece of iron grinding another until both hold an edge. Sparks are part of the process.
