Figured out a likely root cause of my focus problem post-run the last week or so: while listening to the audiobook will be financially beneficial (Graham's THE INTELLIGENT INVESTOR – I sort of get this stuff now; and hey, if Warren Buffett considers it the best book on investing, who am I to argue), it was not creatively so: the morning run is my walking (running) meditation and, for better or for worse, I need that time to be alone with my brain, my breath, and the sounds of the AC. Filling my brain with the words and notions of others, no matter how beneficial (and surprisingly refreshing, in its way) is not at all worth the frazzled, unfocused husk that returns. Duly noted.
