What time of day do you feel you do your best work?
Early in the morning (4am-8am), or late at night (11pm-3am)?
For me, I guess I work well late at night.
The reason I ask this is that I was reading about the meetings between Harry Truman and Winston Churchill during WWII. They had some trouble getting things done when they met together. Truman, a past farmer, liked to get up before dawn to start his work, while Churchill liked to work late into the night and wake up late the next day.
As a side question, how many consecutive days have you gone without sleeping? I had a chemistry teacher who said he went 4 days. For me, just 1.
