Choose a book that has 300 or fewer pages. Attempting to read a very long book in just one day can be overwhelming.
Set aside an entire day on your schedule just for reading if this is your first attempt at completing one book in a day. This will help you to enjoy the book at your own pace from morning to night without pressure.
Carry the book with you everywhere you go. Once you have completed one book in a single day, consider taking on the same challenge on a typical day without erasing all of your plans. Keeping a book with you at all times is key to this challenge.
Start reading before you get out of bed in the morning and finish your reading in bed before you go to sleep at night.
Read throughout the day during usual activities such as during eating, waiting, exercising and commuting on a train or subway.
Read every spare minute you have, and substitute reading for such activities at watching television or surfing the Web.
