Blame and Criticism

In Korea, we use blame and criticism as same words. But it is totally different. The lexical meaning of blame is “to accuse of being at fault; condemn (for something); censure, or the act of blaming; accusation; condemnation; censure”. And the lexical meaning of criticism is “the act of making judgments; analysis of qualities and evaluation of comparative worth; esp., the critical consideration and judgment of literary or artistic work, or A critical comment or judgment.” It seems there is not that big difference between blame and criticism, but there is huge difference between blame and criticism. Blame could be cursing and just telling badly. It is literary bad. In other words, we can blame something nicely. But criticism, it is not only cursing or telling badly. It is opening the better way for something and furthermore, making a good decision.
But too much criticism can be poison. The criticism without valid reason degenerate just blame and too much criticism could be discouraging. Criticism has to be fulfilled like sprinkling salt. Too much salt is salty, and too less salt is bland. It has to be done carefully.
