Popular pictures of Mark Twain show the American man of letters in a relaxed slump, enjoying a cigar, and sheepishly scanning a warm summer afternoon in a comfortable, white linen suit. A calm, restful smile resides on Twain’s lips and his wild, white hair appears to have recently departed from a goose feather pillow.

On first glance, Twain doesn’t seem like a very productive soul, but you can’t judge a book by its cover.

The fact is Twain was a steady, consistent, and productive writer who tirelessly worked on his craft. There’s a reason why Hemingway called Twain’s most popular book, Huckleberry Finn, the root of all modern American literature.

Twain’s impressive work rate is the result of his happy outlook on life and his unique principles. Even if you aren’t a writer, the following list of Twain’s productivity tips will help you work harder and smarter:

1. Don’t be a perfectionist:

Twain observed, “I don’t give a damn for a man that can only spell a word one way.” Twain didn’t let misspellings and rules of grammar get in the way of his storytelling. He believed in telling simple, humorous tales. Twain left the editing to the editors. This carefree attitude spurred his creativity and let him develop his own style that wasn’t beholden to established rules of fiction

Don’t waste all of your time editing and making things perfect. Give yourself time to be sloppy, creative, and messy. It gives you the opportunity to express yourself without barriers. You can edit, retool, and tweak later.

2. Mind your company:

Productivity isn’t always about waking up early, setting a schedule and trying your best to ignore your email and phone. Sometimes it boils down to confidence and Twain believed only certain people inspire self-assurance.  Twain writes, “Keep away from people who try to belittle your ambitions. Small people always do that, but the really great make you feel that you, too, can become great.”

Ignore the naysayers, the cynics, and the folks who are always sucking their teeth whenever a new idea is brought up. They are the “small people” and all they want from you is to join them in their misery. You must associate with people who allow, encourage, and demand big dreams.

3. Laugh at work:

Everyone has their favorite Twain joke. Mine is, “Be careful about reading health books. You may die of a misprint.”

Twain knew that humor, jokes, and laughter soothed many headaches and ills. “Humor is the great thing,” Twain writes, “the saving thing. The minute it crops up, all our irritations and resentments slip away and a sunny spirit takes their place.”

If you have a mountain of work and stress dogs your daily life than take time to seek out humor. Laughter will help you relax. Once you’re relaxed you can get back to work with more clarity and focus.

4. Develop good habits with incremental steps:

Twain knew that good habits are hard to acquire. While it’s easy to say you’ll get up early and visit the gym, it’s another thing completely to obey your screeching alarm clock before the sun begins its day.

Twain had a hack to instill good habits and it goes as follows, “Do something every day that you don’t want to do; this is the golden rule for acquiring the habit of doing your duty without pain.”

He went on to observe, “Habit is habit, and not to be flung out the window by man, but coaxed downstairs, a step at a time.”

Twain knew that one can’t simply pull a positive habit out of the blue. Good habits have to be worked at incrementally.

Twain also writes, “The secret of getting ahead is getting started. The secret of getting started is breaking your complex and overwhelming tasks into small manageable tasks, and then starting on the first one.”

Don’t jolt your system into new, better habits. Gradually work your way into them so they stick.

5. Don’t follow conventional wisdom:

Twain didn’t believe in dieting or maintaining a healthy lifestyle. He smoked cigars, he drank, and he didn’t believe in abstaining from fattening foods.

When it came to cigars he had an especially large appetite. He writes, “I ordinarily smoke fifteen cigars during my five hours’ labors.” It is not exactly a habit one should replicate, but it illustrates that Twain allowed himself small pleasures while he went about his work.

There’s no rule forbidding yourself from small pleasures while you toil over your projects. Faced with a monumental task one should bear down and get to work while allowing for the odd indulgence.

After all, Twain writes, “There are people who strictly deprive themselves of each and every eatable, drinkable and smokable which has in any way acquired a shady reputation. They pay this price for health. And health is all they get for it. How strange it is. It is like paying out your whole fortune for a cow that has gone dry.”
