This is episode 4 of the animated series, “Public Speaking 101.” Ideas change everything — and since language lets us share our ideas, learning how to use it well gives speakers the power to inspire people and even change how they think. This 11-episode course will teach you how to identify, develop, and share your best ideas, while mastering essential communication skills along the way. [Directed by Tolga Yıldız, Kozmonot Animation Studio, narrated by Alexandra Panzer, music by Salil Bhayani, cAMP Studio].
