Morning Person vs. Night Person: Who's More Likely to Succeed?

Instead of hating those cheery morning people who get up singing at the crack of dawn, you should be thanking them for the inspiration.

If you're a night person, you will be less than excited to hear about a recent study that reveals that people whose performance peaks in the morning are better positioned for career success because they're more proactive than people who are at their best in the evening.

That's according to Christoph Randler, a professor of biology at the University of Education in Heidelberg, Germany. He surveyed 367 university students, asking what time of day they were most energetic and how willing and able they were to take action to change a situation to their advantage. A higher percentage of the morning people agreed with statements that indicate proactivity, such as "I spend time identifying long-range goals for myself" and "I feel in charge of making things happen."

But all is not lost for night people. "Though evening people do have some advantages -- other studies reveal they tend to be smarter and more creative than morning types, have a better sense of humor, and are more outgoing -- they're out of sync with the typical corporate schedule," he told the Harvard Business Review. "When it comes to business success, morning people hold the important cards."

Randler says that morning people tend to get better grades in school, which helps them get into better colleges, which then leads to better job opportunities. "Morning people also anticipate problems and try to minimize them," he adds. "They're proactive. A number of studies have linked this trait, proactivity, with better job performance, greater career success, and higher wages."

So how easy would it be to change from a night person to a morning person? You have about a 50/50 chance of that, according to Randler. He says about half a person's "chronotype" is genetic, and in the studies he's conducted where participants try to change, only about 50 percent were successful. One of the most useful ways to change involved going outside earlier in the morning light. If you go outside only in evening light, you will become more of a night person.

It also changes with age. "Children show a marked increase in eveningness from around age 13 to late adolescence, and, on balance, more people under 30 are evening types. From 30 to 50, the population is about evenly split, but after age 50, most people are morning types," Randler said in his HBR interview. He also says that it has less to do with the amount of sleep you get, and more to do with the time you go to bed. Go to bed earlier, get up earlier: It can be as simple as that.

For more information about Randler's studies, see the Harvard Business Review website. But if you really want to ingest his information and make it work for you, you'll read it in the morning.
