I totally agree
But then again , I think if we are sincere to learn , I think we need to be our modest self and accept all criticisms but at the same time , not letting our confidence and faith go down the hill .
Some people are pure harsh mentors , straight to the point , blunt , old school style criticisms. But if you can reflect on their comments and improve from there , I think its a real value add to us.
The harshest mentor will make you grow fastest. Having said that , that style is quite difficuly to work in current context , where people no longer buy the mentor - student style of relation. In fact , people doesnt like to hear criticism but only praise. So now , instead of saying " This is rubbish" , we need to say " I think its great , but you need to be ....."
Hence , I think feedback needs to be given constructively , must let the reader reflect and see a perspective that he had missed out . And when receiving feedback , never take it personally , and see it as a challenge for you to move on.
