The best advice leaves room for circumstances the adviser never experienced.

Any adviser is working from a sample of one life, in one era, with one set of advantages and constraints. Advice that ignores this arrives as a rule and breaks on contact with a situation the adviser never faced. The better version comes with its conditions attached, so the other person can tell when it applies.

When you give counsel, say what it depended on in your case. When you receive it, ask the same question. Knowing the conditions is most of knowing whether to use it.
