It's hard for me to give an accurate judgment of the people trying to give you advice without knowing them, the advice they are trying to give, and the context it's given in. Maybe they are full of crap, or maybe they are the ones that are right after all. Without knowing that it's hard to figure out the situation.
If you really don't want their advice the best solution is to ignore them. That might end good or bad for you.
