What are some potential challenges a speaker might face when trying to establish a human connection with the audience?

The lessons from the TED Talks guide can be applied to improve public speaking in today's digital environment by focusing on creating a human connection, even in a virtual setting. This can be achieved by maintaining eye contact with the camera, using body language effectively, and showing vulnerability when necessary. Additionally, the content should be designed in a way that it pulls in the listener, rather than pushing information at them. This involves making the content engaging, interactive, and relevant to the audience's interests or needs.

A business leader can apply the public speaking techniques discussed in the TED Talks guide during a company presentation by first establishing a human connection with the audience. This can be achieved by walking confidently onto the stage, making eye contact with a few people in the audience, and smiling. If the leader is nervous, admitting it can help build audience trust as vulnerability can be a powerful tool in establishing a connection. The key is to pull the audience in with the message rather than pushing information at them.
