A limit automatically forces you to be creative because now you have to come up with a way to get around it.
Limits can be financial, biological, social, or even made up.
When Steven Spielberg shot Jaws, he wanted to get an animatronic shark, but it was too expensive at the time. To get around this limit, he decided to film from the shark’s point of view, making the movie scarier than it could ever have been with some mechanical model. Ultimately, this is what made the movie a big hit and sparked a whole new point-of-view genre in horror movies.
