When Should You Give Unsolicited Advice?
It doesn’t matter what experience or education you think you have, just don’t do it.
You don’t have the needed information to ensure that your “advice” will be helpful. Because of this your information could make things worse.
Most people, myself included, do not like making things worse.
If you still feel the need to open your mouth, start by asking questions first. Learn about that person. You might find that they don’t need your help at all.
