A. Whatever time works for you,
When teaching adults to write nonfiction, I often ask when they prefer to write. The most common answer is 2 hours after awakening. The second-most-common time is late at night, when most other people are snoring. Occasionally people set an alarm for 2 a.m. and write until their eye-drops run out.
Morning is best for me, by the way. But it’s also the best time for me to go to the gym. If I don’t walk the treadmill first thing, I never do. If I delay writing in the morning, though, I always make time later. So I go to the gym as early as I can, then write.
The only reason to think about your best writing time is so that you can articulate it. Then build your life around it.
Now a question for you. What is your best time? How can you build your day around that time? Can you post a sign on your cube from 8 to 9 a.m. – or 3 to 3:45 p.m. – that says, Writing in progress? Can you find a quiet corner near your office or office building where you can hide out frequently?
Most important: Find the best time of day for you to write. Then write then.
