The question is not so much whether you do or don't burn the midnight oil, because as a freelancer you may simply have to, but when are your most productive hours? I recently heard from a specialist that human brain is programmed to productively focus on work for only four hours a day. So it is important to exploit those hours as much as possible.

Here is a little story from http://www.slate.com/id/2193208/:

When I told my friends I had found a way to transform myself into a morning person, they responded in one of two ways. The night people leaned in as if I were about to reveal the location of a stash of pirate gold. The morning people simply regarded me with pity and wonder. "I just don't understand why it's so hard," said one friend, a Danish medical student. "I can get up anytime I want."

This sort of smugness is prevalent among morning people, who count among their ranks Nelson Mandela, Mahatma Gandhi, nearly every American president, and even Jesus. (See Mark 1:35: "And in the morning, rising up a great while before day, he went out, and departed into a solitary place, and there prayed.") Night people are stuck with psychopaths like Adolf Hitler and Juan Arreola, the guy in Pennsylvania who nearly killed his girlfriend's 2-year-old last year, explaining to a judge, "I'm not a morning person."

So when are your most productive hours? When do you concentrate the best?

NOTE: ON THIS POLL, THE TERM "EVENING" MEANS EVENING AND/OR NIGHT.
