Setting a timer helps many writers become more productive. Start with a short period of time – anywhere from 15 to 30 minutes. When time’s up, take an even shorter break – anywhere from five to 10 minutes. During the break, do something physical. Taking a short walk, grabbing a bite to eat, dancing to your favorite song, even household chores will get the blood pumping, stimulate your senses and rejuvenate you for your next writing stretch. Avoid tasks like watching television, reading a book, checking social media, surfing the web – they’re apt to sap your focus away from the story in your head.
When your break is over, reset the timer and repeat. Try extending the writing time to break time ratio. If you wrote for 15 minutes and took a 5-minute break, try writing for 30 minutes with a 10-minute break. Keep tweaking the ratio until you find the most productive method for you.
