What should you do when someone keeps telling you how good they are?

When someone repeatedly tells you how good they are, it's best to respond with a mix of acknowledgment and redirection. You can compliment their achievements if appropriate, but also steer the conversation towards more meaningful topics or shared interests. If it becomes excessive, consider gently expressing that you appreciate their confidence but would love to hear more about their experiences or challenges instead. This approach can help shift the focus while still being respectful.
