12 Things Successful People Do Before Breakfast

"If it has to happen, then it has to happen first," writes Laura Vanderkam, time management expert and author of "What the Most Successful People Do Before Breakfast."

Those among us who have managed to find professional success and eek out a life actively embrace this philosophy. They must set aside their first hours of the day to invest in their top-priority activities before other people's priorities come rushing in.

Science supports this strategy. Vanderkam cites Florida State University psychology professor Roy Baumeister's famous finding that willpower is like a muscle that becomes fatigued from overuse. Diets, he says, come undone in the evening, just as poor self-control and lapses in decision-making often come later in the day. On the other hand, early mornings offer a fresh supply of willpower, and people tend to be more optimistic and ready to tackle challenging tasks.

So what do successful executives and entrepreneurs do when they are rested and fresh? From Vanderkam's study of morning rituals, we outline the following 12 things that the most successful people do before breakfast.
