We've been talking about how wisdom comes from God. It is a gift from God available to all of us. There's another way for us to attain it. It still comes from God, but Proverbs says, "Whoever walks with the wise becomes wise" (13:20).
So, speak with wise people. Listen to wise people. Ask wise people questions. Eventually, you'll be all the wiser. You'll be asking wiser questions. People may start asking you wise questions.
