Be wise, my son, and rejoice my heart. And I return my reproacher a word.

The verse centers on "wise", "rejoice", "heart", "return", "reproacher", and "word". It is saying that the verse draws attention to "wise" and "rejoice", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 10's "Thine own friend and the friend of..." into verse 12's "The prudent hath seen the evil he...", so "wise" and "rejoice" belong inside that flow. In Proverbs context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "wise" and "rejoice" with trust shaped by these words, not by a vague optimism outside the passage.
