The president paraphrased German philosopher Friedrich Nietzsche as he borrowed a metaphor to describe his cancer struggle, calling it "my longest and steepest hike."
Chavez referred to his health only briefly, instead focusing on government projects from subway expansion work to public housing complexes. The program seemed aimed at projecting a business-as-usual image of the president at work.
Chavez spoke energetically while signing documents to approve spending. He paused for televised appearances by his vice president, who spoke from a government-run chicken farm alongside Chavez's brother in Venezuela, and his health minister, who appeared leading a tour of a Venezuelan hospital.
In the hospital, Health Minister Eugenia Sader passed the microphone to a boy, who repeated a slogan that has been used frequently by the president's supporters: "Onward, Comandante."
The program was recorded earlier Sunday and lasted more than two hours. In his typical style, Chavez flipped through a book on socialism, laughed with his aides and briefly broke into song.
He also read aloud a get-well note sent to him by a young girl.
"I promise you I will keep getting better," Chavez said.
