Criticism.

First at all I want to say hello to everybody, as we know everyone criticisms the words or work of your partner but Do you know how to say a  good criticism? the common mistakes that everybody makes are: Style, Grammar and the Kind of of critic. 
This are going to be very useful because in the work, in the school and even in your house you can use it and develop therefore it is very important to say in a good way. 
As I said the Style is a common mistake. Long sentences is a problem because it is to long and lose the effect of the criticism. Lack of details it is a huge problem because you are not saying everything hence are going to produce that the person do not understand and probably are going to commit again the same mistake. Informal language such as use personal pronouns for example I think, I feel or we wonder. 
Grammar it is another important issue. When you are going to say a criticism it very important that you avoid grammar mistakes, spelling mistakes or pronunciation mistakes. If you commit this mistakes the person are going to think he, she or they are criticize me but they do not know how to speak english. 
The Kinds of criticism are: Constructive, Negative, Positive and Effective. 
Actually I believe that the best criticism are the constructive because this kind of criticism are going to help to develop yourself and to say to people that they are not developing a good role in your team. 
I this advices will help you in your professional and personal life.
