Chimamanda Ngozi Adichie is a Nigerian writer and public speaker who addresses social issues such as gender, race and social status.

At the age of 19, Adichie left Nigeria and went to the Unites States to study communications and political science. As a student, she first experienced what was like to be identified by the color of one’s skin or by one’s origins.

Those experiences drove her to learn more about race as an idea, stereotypes, and also feminism. Over the years, she has written several critically acclaimed books like Purple Hibiscus and Half of a Yellow Sun.

However, it wasn’t until her TED Talks went viral that people really knew about Adichie – The Danger of A Single Story is now one of the most-viewed TED Talks of all time, and for a good reason. With incredible wit and eloquence, Chimamanda tells the story of how she found her authentic cultural voice and how a single story of a person or a country, can lead to critical misunderstanding.

Here are 15 Chimamanda Ngozi Adichie quotes on shared assumptions and their negative effect.

The single story creates stereotypes, and the problem with stereotypes is not that they are untrue, but that they are incomplete. They make one story become the only story.

I think you travel to search and you come back home to find yourself there.

Culture does not make people. People make culture.
