How about an abstract inspiration for persistence in love and relationships? Check out The Dot an the Line: A Romance in Lower Mathematics, an award winning short film by Chuck Jones based on the book by Norton Juster.
Title: The Dot And The Line
The Dot and the Line: A Romance in Lower Mathematics is an adorably quirky take on dating and love. It seems the poor protagonist of this picture, The Line, is just too much of an old square to attract his perfect circle, who is far more interested in the free-spirited squiggle. But with a little bit of persistence and a willingness to push himself, its The Line that walks away with the spoils in the end.
