A good adviser knows when the missing information belongs to someone closer to the situation.

Advice fails more often for lack of facts than for lack of wisdom. Someone standing outside a problem can see its shape, but the details that decide the answer sit with the people living inside it, and a confident recommendation built on the wrong details does harm while sounding helpful. Knowing where your knowledge ends is part of being useful.

When someone brings you a question this week, notice what you would need to know to answer it properly. If that knowledge sits with them or with someone nearer, say so and help them go and get it. Pointing at the right person often beats producing an opinion.
