This quote is a metaphor comparing the interaction between harsh advice (the hammer) and the person receiving it (the anvil). Just as an anvil repels the force of a hammer, harsh or severe advice often fails to have the desired effect on the person it’s meant for. It suggests that harshness, rather than encouraging change or growth, often causes resistance and defensiveness.

The hammer and anvil metaphor is particularly apt as it captures the dynamic nature of this interaction. The hammer striking the anvil causes a reaction – the anvil doesn’t passively absorb the blow, but repels it. Similarly, harsh advice doesn’t passively sink in; it provokes a reaction, often of rejection or resistance.

In today’s world, this concept can be applied in many areas, such as leadership, parenting, education, and personal relationships. For instance, a leader who constantly criticizes or berates their team is unlikely to inspire them to improve. Instead, such an approach may create a defensive, negative environment. The same can be said for parents or educators who resort to harsh criticism or punishment in an attempt to correct behavior. The recipient of such treatment is likely to become resistant rather than receptive to change.

In terms of personal development, this idea suggests that self-criticism or punishing oneself for mistakes or shortcomings is not the most effective path to growth. Instead, a more compassionate, understanding approach is likely to be more successful. This can be seen in the growing recognition of the importance of self-compassion and positive reinforcement in psychology and personal development fields.

Moreover, understanding this principle can help in interpersonal communication. When we want to help or advise others, it reminds us to do so with kindness and empathy, rather than severity, to increase the likelihood that our advice will be received and acted upon.
