When I was growing up in South Florida, my father would often drive our family down to the Florida Keys to go fishing. The Keys, as they are known, is the chain of islands strung together by hundreds of bridges and stretching all the way down to Key West, which is situated at the southernmost tip of the continental United States.

I often heard the name Ernest Hemingway mentioned in the conversations between my parents and their friends. Hemingway was--and still is--a legend there. He spent a lot of time in Key West, and would often fish there and in nearby Cuba, just 90 miles due south.

What I didn't know at the time was that, besides taking boats out into the Atlantic to go deep sea fishing, Hemingway also liked to write while sitting on a boat anchored just off the coast of Key West. It was the perfect place to get away from the crowd and focus on his writing.

This is just one of the surprising facts about Hemingway and other great writers that I discovered in Process: The Writing Lives of Great Authors, by journalist Sarah Stodola. In her book, she examines the techniques, habits and inspirations of 18 of the greatest writers of the 20th century and today.

Most of the writers she studied are very regimented in their work routines. They stick to strict daily schedules, and hone a lifestyle around their writing career. Most of their lives are less glamorous and far more prosaic than most people imagine.

Some of the writing routines she describes seem ordinary. Others are of the quirkier sort. Here are some of the "productivity hacks" that are used by six of the authors she profiles in her book:

1. Margaret Atwood discovers some of her best ideas while doing housework.

While not spending time on the popular writing app Wattpad, or chatting with readers on Twitter, Margaret Atwood gets some of the best ideas for her novels while doing housework and other rote chores. "I think it induces ideas to do a repetitive activity that is not connected with writing."

2. Vladimir Nabokov wrote in bathtubs and in the back seat of his car.

Nabokov and his wife stayed at motels while they were on a road trip through the US. It was at this time that he was writing Lolita, the book that would bring him massive commercial success and enable him to retire from his teaching job at Cornell and move to Switzerland. To work effectively, Nabokov needed absolute silence, which he sought in the confines of bathtubs and the back seat of his car.

3. Toni Morrison plotted her first novel while her young children were playing around her.

At the age of 35, newly divorced and with two young children to raise, Toni Morrison would get up early in the morning to write. While taking care of her kids, she would mull over the storyline and characters for her first novel, The Bluest Eye, which took her five years to write.

4. Jack Kerouac wrote on 120-foot scrolls.

To avoid having to stop writing after he reached the end of each page in his typewriter, Jack Kerouac wrote his first novel On the Road on a 120-foot scroll over the course of a drug-fueled three-week period (which he accomplished after planning the book for the previous three years).

5. Virginia Woolf developed her stories during her daily walks.

Virginia Woolf would plot out her stories while taking her daily walks in and around London. She also wrote consistently in a diary to not only practice her writing, but to plan her writing.

6. James Joyce wrote less than 100 words a day.

James Joyce wrote an average of just 90 words a day, based on the eight years it took him to write the 265,000 words in his novel Ulysses. Before Ulysses, it took him ten years to complete his first two books, Dubliners and A Portrait of the Artist as a Young Man. Joyce may have broken the record for lowest daily word count of any author. But he didn't give up.
