All of the Cancerian spaces are ruled by the moon, which brings up themes around nurturing and healthy (or unhealthy) growth. Based on the Chaldean order rulership scheme, the ruler of Cancer II is Mercury. The Triplicity scheme ruler is Mars. The babies that grow in this particular lunar-ruled space are often Mercurial constructs, and the Martial influence can become relevant when mental babies grow up and overpower their creators.
Werner Herzog has both his natal Moon and Jupiter in Cancer II. His films often address these issues of protected growth and nurturing, and the unexpected outcomes of such nurturing. In Even Dwarfs Started Small (1970), inmates of an asylum isolated on a remote island rebel against their caregivers and cause mayhem including food fights and fires. The filming of 1982's Fitzcarraldo, (a film about a man who refused to give up on his visions) involved a great deal of violence and multiple deaths, and included having the cast pull a 320-ton steamship over a muddy mountain. And then, of course, there's Grizzly Man (2005).
Jupiter is exalted in Cancer II, and Herzog has certainly made a success of his commitments to being a conquistador of the absurd. In 2009, Time magazine named him one of the world's 100 most influential people.
As the Sun flows through Cancer II this year, especially with the ongoing Saturn-Uranus pressures, be mindful of how the things you are working to create are going to function once they are unleashed in the world. Unless you have dignified planets here, in which case, feel free to go full-on Don Quixote. It will probably work out well for you.
