Good things happening to another can never block good things coming to us. All writers are at different stages of developing the knowledge of their craft and all have different areas of expertise and knowledge. The process of giving feedback is the sharing of this knowledge with one another as it relates to a specific piece of writing. The whole point of giving feedback is to help a writer improve. There is no single way to give feedback.
Some people prefer to read the piece once, making comments as they go along.
Others prefer to read the piece once in its entirety without thinking about details in order to form their first impressions and then reread with their red pens out. Many people choose to insert their comments throughout it in a clear, distinct type in the same way, as an editor would work with a manuscript. Others prefer to refer only to the parts they are discussing. Often people experienced in giving feedback will use both at different times, depending on the depth of the feedback. The goal is to help another writer improve.
