Dear sir!
I am much impressed by your behavior and character more than your article. It is your generosity that you always look forward to sharing your experience with everyone,so that other people can benefit from it. The true advice can be given to the same person who has knowledge and experience in that subject matter.I want to mention about the person who had asked for advice on the loss of business, and you gave the correct advice, but he did not follow your advice. Because of which he had to be ashamed twice.A person does not want to adopt a permanent and successful path. That is why knowing that you are so experienced, he did not follow your guidelines properly. Advice should always be taken from the experienced person.On this subject you have presented a good example of parents. Always look forward to receiving knowledge and experience wherever available.
I have tried to answer the question you left below-
Therefore, people repeat the mistakes that they do not take advice from a person with a specialist and experience. If we take advice from a person with the right experience, then the chances of repeating the mistakes remain low. As the person doing damage to the business had consulted with you, but did not follow the things you said, because of which he repeated the mistake twice.
Regards.Have a nice morning.☕
