From the Chronicle: Vitae
When you write first thing in the morning, and then stop writing for the rest of the day, your mind will continue to process thoughts related to your project. Take advantage of that. One of the best ways is to go for a walk alone and without any electronic devices. Use the time to process your thoughts. Think back on what you have written for the day and about what you will do the next day. You may be surprised about the revelations you have about your writing when you are not writing. You may even wish to take a notepad with you on these strolls.
This is really a great article. But with all articles like this the insights gleaned are useless unless you (I) act upon it.
