A manifesto is a public declaration of your intentions. It’s a simple articulation of what you believe and a vision of the world that you wish to create.
Whether you realize it or not, some of the speeches and documents that have most shaped the world could be called manifestos:
Martin Luther King Jr.’s “I Have a Dream” speech casts a vision of the world the MLK spent his life working to create.
The Declaration of Independence is an articulation of what the founders of the United States believed about humanity, and their intention to be free from outside rule.
