Winter can be hard. I loathe the whole concept of "Daylight Saving Time" -- ha, more like daylight wasting time. If the clocks hadn't changed, I'd still have that hour in the evening. For a while I was able to go ride before my afternoon classes, but once the work load started piling up, I had too much to do and too little time to do it. At least the semester is over and I'm starting winter break, that should give me some breathing room.
Chin up, the days will be getting longer again before you know it.
