Barack Obama exercises in the morning and he gets to the office around 8:30. The president works till about 6:30 p.m. and, after work, he has dinner with the family, hangs out with the kids and puts them to bed about 8:30. Obama reads briefing papers, does paperwork or writes stuff until about 11:30 and he also reads a book before he goes to bed. But, what most people don't know is that he doesn't do all his day-to-day work in the Oval Office. He prefers to edit speeches and review papers in the President's Study, instead. The White House receives about 20,000 letters and emails every day and, sometimes, citizens are surprised by a personal response from Obama himself.
