I've always been very good in the very early morning. That's when I can hit the road for cool hikes and productive fishing trips, when I can read a book and remember what I read, when I can write a brief without pausing for worry and writer's block. It's the time when my commute to work shortens by 15 minutes, for want of traffic.
When I am in the mode in which I do this a time or two a week, I wonder why I ever fail to get to work by 6:30 a.m.
