Everyone knows the old saying "The early bird catches the worm." When it comes to becoming successful in business and in life, it appears that the old saying might just be true.

Business finance company Fleximize recently put together a study of the morning habits of some of today's most successful people. No surprise, many of these people were out of bed and well into their days by 6:00 a.m.--and some even before that.

Here are the morning habits of 9 remarkably successful people.
