A good mood in the Motor City.
I'm currently in Detroit taking a two-day course in the newest version of Pro/Engineer, called "Wildfire 2.0". I am in a tremendously good mood, full of energy, and remarkably at ease. Throughout the day, i have been ruminating about physiological explanations for this ebullience: i must have slept well last night, perhaps i just operate well in the cooler temperatures of this place, the mile of walking first thing in the morning from the hotel to the office building, etc.
All of a sudden a little voice intervenes: "It's spring and you're happy. You don't need to explain it, just enjoy it!" Okay, i think i will.
