This quote suggests that our inner thoughts and judgments should be kept private, while our outward communication should align with societal norms or expectations. It implies the importance of discretion and tact in our interactions with others.

The idea of keeping our thoughts secret doesn’t necessarily mean being dishonest or insincere, but rather suggests that it’s often wise to keep our innermost thoughts and judgments to ourselves, as they may not always be well-received or understood by others. This can help maintain harmony in our relationships and social interactions.

On the other hand, "talking like the people" suggests that we should communicate in a way that resonates with others, using language and ideas that are familiar and acceptable to them. This can help us connect with others, convey our ideas effectively, and avoid unnecessary conflict or misunderstanding.

In today’s world, this idea can be applied in various contexts. For instance, in professional settings, it’s often important to present our ideas in a way that aligns with the company’s culture or the industry’s norms, even if our personal thoughts or judgments are different. Similarly, in social or political discussions, it can be more productive to express our views in a way that is respectful and considerate of others’ perspectives, even if we strongly disagree with them.

In terms of personal development, this idea can help us develop our communication skills and emotional intelligence. It encourages us to be mindful of our thoughts and judgments, and to consider how we express them to others. It also reminds us that we can maintain our integrity and authenticity, while also being tactful and considerate in our interactions with others. This balance can lead to more effective communication, better relationships, and greater personal growth.
