The person asking for guidance needs your relevant experience, not your confidence about everything.

Being asked for advice is flattering, and the flattery tends to widen the answer. A question about one specific decision turns into your views on careers, money, and how people ought to live, most of which you have no particular standing to hold. What actually helps is the narrow part you have lived through, including where it went wrong.

Start by saying what you actually did and what it cost. Mark the edge of your experience out loud. Beyond that edge, ask questions instead of offering more certainty.
