Criticism is destructive. It breeds antagonism because it stems from the wrong approach - from the focus on mistakes. Criticism could be a short-term band aid but is almost always a long-term parasite. It undercuts the future.
Feedback is constructive. It stems from the partnership perspective- from the focus on expanding the pie without sugar-coating the shit. Feedback can be painful in the short-term because it is sometimes indirect and subtle. But it is almost always a long-term seed for success. It feeds the future.
