Our parents, they love us, and in areas in which they are inexperienced,Their advice is always going to be based on opinions and good intentions, not in facts and experience. I like that statement. But for those who would seek advice from an experience person in a particular field and chose to do a different thing, they thought that in addition to your advice they might have discovered something new or a little different which they would want to try and hit a success that will most likely surpass what anyone has achieved on that field, that is why they would keep asking for advice and keep doing something different not knowing what they were doing was not a little different but far far different from what they were advised.
