Arrogance (un-humility / not appreciating your own limits) is not the only reason one may reject advice. Unless the person giving the advise is already respected/revered for their knowledge by the person receiving the advice, then there is no reason for them to value the advise received over whatever their original plan of action was. This is [1] from the post. Bad advice exists, and if you cannot differentiate it, you must experience the reason for it. In which case, experiencing the scenario for the advise validates the need and usefulness of the advice.
