text: The second reason you should get more than one persons advice is that they might not be correct. It might not be correct because you didn't hear from more than one person so then you only know what they think is correct and that might be incorrect. It also might not be correct because you only know what they want you to know so then you cant be sure of what the truth actually is. Your information might be incorrect because you only heard from one person, you only know what they know, and they might not be telling the truth.
