Advice becomes useful when it respects the difference between guidance and control.

Guidance offers a view and leaves the decision where it belongs. Control offers a view and treats any other choice as a failure. The difference is felt immediately by the person receiving it, and it determines whether they come back to you honestly next time or start managing what they tell you.

After giving advice, notice whether you need it taken. If you do, say less and ask more. Advice that can be declined without cost is the only kind that gets heard properly.
