I've discovered over the past few years by studying for hours and hours on end that I really only think well in the mornings. I can start studying as soon as I get out of bed and stay really sharp until mid-afternoon. At that time, though, my ability to focus, comprehend information, and solve problems starts to plummet. Are there any specialties that would cater to this type of rhythm? Doctor jobs in which I can do all my thinking in the morning? ...or am I going to fail as physician because I can't stay mentally alert for 36 consecutive hours?
