The easiest way to create a new habit is to make it one of the first things you do each day. As each new day progresses, you can be pulled in a number of different directions. There are simply too many distractions that come on once the day is set in motion, not to mention the fatigue that can overcome you after lunch.
What you resolve to do first thing—or at least early in the morning—you will do. It is so much easier to sit down and write a page or two and then conduct your daily business than it is to check e-mail, pay bills, return phone calls, wash your hair, wash your dog, and get pulled into half a dozen different tasks before trying to write a page or two. This is why many people exercise first thing in the morning. For the next 30 days, your exercise is writing.
