Today was quite a productive day. I attribute it to being well-rested and guilt-free about it. But I think the real clincher was this: I got out of the house early enough to be in the sun. So maybe it is Season Affective Disorder that I was experiencing. Being in the dark sucks.
This reinforces the need to have a regular early morning schedule to maximize exposure to the sun in these dim New England winters. It started to get dark around 400PM, which is awful. As it was today, I left the house at around 1130AM; shooting for early-morning stint at Starbucks will be better. AND, it will give me the necessary anchoring activity.
