> I really, really enjoy my sleep :). This is certainly very practical advice, but it requires that I'm disciplined enough to go to sleep earlier the preceding night. That's difficult but certainly possible. I think most people can relate. :) I grew up with 8AM class throughout my childhood, so waking up at 7AM was a life-long habit when I got to college. And then I dropped it completely — I started sleeping from after 4AM until noon or so whenever I could. At some point that got balanced out by more 8AM classes (and 5AM coffee shop shifts, but that's another story), but after college I fell into the less-than-ideal pattern again. What worked in the end was simply setting the alarm clock and getting up, even when that meant I was effectively a zombie for a few consecutive days. At some point my body started giving up and going to bed at 10PM became the norm. These days it's anywhere between 9PM and 11PM on average, with a 6AM alarm clock even on the weekends. I spend my mornings either at the gym or doing something else productive (like side projects). Evenings are reserved for relaxation.
