We've all heard cliche's like "The early bird catches the worm." That, apparently, is a lot of crap. Two recently published studies indicate early risers aren't necessarily more productive than folks who prefer to sleep in. Brigham and Women's Hospital monitored the sleep patterns, and academic performance of 60 students at Harvard for a month. Their findings indicate consistency is more important than getting up early. Students who go to bed & get up at the same time do better than those with erratic sleep schedules. Another study, at Baylor University, produced similar results, according to time.com.  Yes, Apple CEO Tim Cook gets up @ 3:45 am. Pablo Picasso used to stay up all night. Bottom line: Set whatever routine works for you & stick to it.
