THE TENANTS: A Motivating Novel and Film for Writers

Here's IMDb's plot summary for The Tenants (2005) : 

In an abandoned tenement, an African-American militant writer [Willie Spearmint (Snoop Dogg)] and a Jewish novelist [Harry Lesser (Dylan McDermott)] develop a friendship while struggling to complete their novels, but inner tension rises between the two.

In the film, which is based on Bernard Malamud's novel of the same title, Willie confessed to Lesser, "Man, I tell you, this writing stuff is no joke." And in terms of the life of a writer, Willie said, "Baby, it's a long, hard, lonely life."

Carlos Fuentes, the Mexican novelist and essayist, agreed with Willie when he reportedly said:

You must have discipline for writing. It is not an easy task. It is very lonely. You're all alone. You are not in company [...] You are delving into your depths, but you are profoundly lonely. It is one of the loneliest careers in the world [...] In writing, you are alone. That takes a lot of strength and a lot of will to do it.

If you're a writer and you're having trouble staying motivated and focused. And you don't know how to handle being constantly interrupted by selfish people who don't take your writing seriously, then The Tenants may be the novel and film for you, because Willie and Lesser are two writers who take their writing extremely seriously
