From Chapter 1:
"How much writing do you think you could get accomplished if you had an entire year to spend on just that and nothing else?
And when you think of that year, don't think of several hours a day. Think of every single minute. That you've got the special ability to not require time to sleep or do anything else at all. You wouldn't get fatigued or burned out.
Think you could write a lot in that year? Then consider this: Anything you spend twenty minutes a day on every day is something that you'll spend more than a year of your life doing.
Increase that to an hour a day and you'll spend a year on that activity over the course of only 24 years. That's the amazing power of doing something every day. The time, bit by bit, adds up to a tremendous opportunity to accomplish things that excite us."
