"other times, people that are just critic on everything, it does depend on that as well--- or a person that always is criticizer of specifically 'you' or 'others' or 'something'... those can easily be thrown out the window-- not saying that SOME TIMES they are helpful but usually they aren't and just some one on their high horse (ya know?)...."

that's exactly it, if someone gives real, constructive criticism I will go away, think about it and accept it, but a lot of critics just seem to be criticizing because they can, or because it's your work.
