Sometimes we are weak, we do not believe in ourselves and therefore wait for other’s approval, in order to feel right. Even if we are in a fragile_condition, we cannot avoid criticism, you know “do this…do that…don’t”. Criticism that damages, well intentioned or ill, is the one containing no saving kernel or truth yet has a certain plausibility that cannot be easily or rationally refuted. So, pay attention to critics to detect a saving kernel. The others are garbage.
