At the risk of this blog sounding like a self-help book, here's another entry about ways to improve:

There are good times of the day for doing certain things, like exercising in the morning. (Actually for me exercising in the morning is truly an act against nature, but I'm experimenting with it.) Or doing totally mundane, near-mindless things like paying the bills just before bed when I'm tired (though I'd rather be reading.) I do my best creative work in the mid-morning, and the afternoon is good for plowing ahead with the yeoman's tasks. I guess it was William Blake who said "Think in the morning. Act in the noon. Eat in the evening. Sleep in the night." Reminds me too much of a marketing quadrant diagram, but I like the general idea.
