Anxiety is the handmaiden of creativity.

Star Wars: Episode I - The Phantom Menace
Captain Panaka: Her Highness commands you to take her handmaiden with you.
Qui-Gon Jinn: No more commands from Her Highness today, Captain. The spaceport is not going to be pleasant.
Captain Panaka: The queen wishes it. She's curious about the planet.
Qui-Gon Jinn: This is not a good idea.
[to Padme]
Qui-Gon Jinn: Stay close to me.
