Do you give attention to those who make comments on your mistakes?

Whether the person is a principled person or erraneous person, I definitely give attention to the criticisms and comments, because they are like self appointed monitors with whose help we can aim at perfecting our lives.

I think that the I told you so people are really annoying when you already know that you made a mistake against the advice of others, I think taht it just makes the situation worse and would be much better if people coudl just support you throughout and try to withold the urge to rub your mistakes in your face as you are suffering from them enough through self torture already.
