Successful people work 4 hours a day: study

It sounds too good to be true: Leave work early for greater success on the job.

Psychological Review recently published a study that claims that the key to success is working hard in short bursts of time.

It comes down to focus and choosing specific tasks over multitasking and taking breaks.

The study found that "deliberate" four-hour violin rehearsals accomplished more than seven-hour sessions of steady practice. The best performers set specific goals, practiced with greater intensity for shorter periods of time, and took planned breaks.

The study graphed their hours of productivity, noting that the most intense periods of work were before noon and again after 4. Eventually they found that successful individuals in other professions mirrored this work-less-for-success model.
