text: The first reason is that people can be biased. Biased people could be your friend, or a parent, and they don't mean to give really advice that doesn't work, but sometimes they just do. A counselor who isn't in your daily life all the time would be less biased and could be a fabulous second option if the first advice was too biased. It is just a good habit to stay away from biased people when looking for advice because nobody needs advise coming from somebody who may just be confused about what the question was. Or they could also purposely give you bad advice so you have to make sure to check that your advice is not biased so you don't take that advice the wrong way and so something stupid or that's not like you.
