There are some frustrating former newsagents in our marketplace. People ready to tell others what to do and how to do it, trading off having been newsagents previously.
Some of these former newsagents who are quick with advice do not have relevant experience on some of the situations on which they provide advice. Some failed when they ran their own newsagency and while this should not preclude them providing advice, it would be helpful for them to disclose this.
My advice to newsagents who are offered advice from anyone including former newsagents is to test their qualifications for providing the specific advice. Ask tough questions, make sure that you can trust their expertise in the field in which they are giving advice.
Sometimes, the best advice will come from an expert in the field of need.
