The first instance of self-criticism can be useful. If it is constructive, it can be a call to learn from your mistakes and be better.
The first criticism can empower you.
Every echo — that is to say the subsequent criticisms that exist merely to beratingly remind you of the same mistake — are needless. The more you entertain them, the more energy that is wasted helplessly ruminating about the past.
Echoes will drain you.
Pushing yourself to grow while maintaining a sense of well-being are perfectly compatible things provided you give yourself permission to pay mind only to the first criticism that serves you and none of the noise that comes after it.
