First, let's talk about Brian Tracy's talk, "Your Body Language May Matter More than You Think." Brian Tracy is a renowned psychologist and speaker who reveals the importance of body language in interpersonal communication through vivid examples and in-depth analysis. He taught us that body language often communicates our true thoughts and feelings better than verbal language. A smile, a look, a posture can be the key to changing someone's perception. This talk made us realize that to be a good communicator, we need to pay attention not only to verbal expression, but also to our body language.

Secondly, Meg Jay's "20 Years Old, Time Never Comes Again" was also a high-profile and famous speech. With vivid and powerful language, she tells young people how to cherish the golden age of 20, seize the time, and plan their lives. She pointed out that twenty years old is an age of endless possibility and opportunity, but also an age of responsibility and uncertainty. If we can clear our goals and direction at this stage, and make full efforts for it, then the future road will be broader and brighter to us.

Simon Sinek's talk, How to Inspire Action: How Great Leaders Inspire People. Simon Sinek is a well-known entrepreneur and speaker who has developed the "Golden Circle Rule", namely the Why, How and What levels. He believes that great leaders always define their mission and values first (Why), then think about How to achieve those goals (How), and finally a specific course of action (What). This speech made us realize that in order to become a great leader, we must first clarify our own beliefs and missions, and infect others with passion and belief, in order to stimulate the cohesion and creativity of the team.

Finally, we cannot ignore Jane Goodall's speech "Why We should Care for Animals and Respect Nature". Jane Goodall is a famous zoologist and conservationist who uses her research on chimpanzees as a basis to call for our attention to animal rights and respect for the laws of nature. She told us that the relationship between human beings and animals and nature is inseparable, and our survival and development are inseparable from the ecological environment of the earth. This speech makes us deeply realize that protecting the environment and caring for animals is not only for them, but also for ourselves and for the future of our descendants.

All in all, these inspiring TED talks not only let us feel the wisdom and passion of the speakers, but also let us see the infinite possibilities of the future of mankind. Let's internalize the wisdom and inspiration from these speeches into our own power and move forward to create a better future!
