In wiving and thriving men should take counsel of all the world.

Marriage and the pursuit of prosperity are consequential enough to warrant hearing many people's views before deciding. A person should not rely solely on private judgment in such matters.

The call to consult “all the world” emphasizes breadth of counsel rather than a literal duty to ask everyone. Advice can inform a decision without transferring responsibility for it to others.

Use the proverb to encourage someone facing a major decision about marriage or livelihood to hear a range of perspectives before committing. Its wording speaks specifically of men marrying, although its counsel can be applied more broadly.
