A parent shaming us by comparing us unflatteringly with a sibling; a boss humiliating us in front of colleagues when a task isn’t up to their expectations; a partner repeatedly complaining about some household task we haven’t done yet: these are all attempts to “light a fire under our ass” in order to get us to achieve more. Most of us have had this ploy used against us so many times over the course of our lives that we’ve internalized this motivational strategy.
Our inner critic punishes us verbally when it thinks we’ve under-performed. It castigates us for being lazy when we haven’t gotten around to starting some task. Yet despite all this internal criticism, most of us still have a hard time motivating ourselves to do things. When self-criticism fails, the answer is usually more self-criticism. “How,” we might wonder, “would I get anything done if I didn’t give myself a hard time?” Source:
