What is a general rule applicable to all communications?

The answer indicates that all listed principles are important in communication. This is an essential understanding because effective communication encompasses a variety of best practices that ensure clarity and engagement with the audience.

Being concise is important as it helps to convey messages clearly and efficiently, avoiding misunderstandings or confusion that can arise from lengthy explanations. Maintaining eye contact fosters a connection with the audience, making the communication feel more personal and engaging, which can enhance comprehension and retention of information. On the other hand, while using technical jargon might be appropriate in specific contexts—such as when communicating with experts in a particular field—it's generally better to avoid it in broader communications to ensure that the intended message is accessible to all parties involved.

Thus, recognizing that effective communication involves multiple strategies, including being concise, maintaining eye contact, and being judicious about technical language usage, reinforces the idea that the most successful communicators tailor their approach to fit the audience and the context of the interaction.
