Drinking a large latte is more likely to succeed.

Bringing a bigger latte into the office could be the key to your next promotion-at least so says one workplace expert.

A large latte may be your next promotion, says one career research expert.

Andrew dress for the job you want, a columnist with the Harvard Business Review, says an emerging body of social science confirms the age-old mantra that the key to climbing to ladder is projecting the image of success-i.e. "dress for the job you want, not the job you've got."

Andrew O'Connell is a columnist for the Harvard Business Review. He points out that more and more social science research confirms the long-standing saying that creating a successful image is the key to your promotion. For example, "Please dress according to the standard of your ideal job instead of your current job."

One study in particular suggests that humans tend to associate bigger food portions to success-just like they buy a bigger house and a bigger TV. Thus, Odyssey 39: Connell claims ordering a bigger coffee, a larger smoothie or even a bigger pizza at the office could signal to co-workers and bosses that you're ready to move up in the world.

A study specifically points out that people tend to associate large portions of food with success, just as they always want to buy a big house and a big TV. Based on this, O'Connell believes that ordering a large cup of coffee, a large fruit milkshake or a large pizza in the office can show your colleagues and boss that you are ready for promotion.

In a 2011 study by a researcher at HEC Paris, witnesses ranked people who were seen choosing larger food items two points higher on a 1-to-7 power and respect scale than those who picked out smaller things to eat and drink. The study doesn't match exactly to thesis-researcher David Dubois was studying how to reduce obesity in poor populations. However, Odyssey 39 + Connell says it meshes well with the concept that employees who want to be successful should surround themselves with the trappings of success.

According to a study from HEC Paris, data show that those who ordered large portions of food and drink scored an average of two points higher than others on the power and respect scale on a 1-to-7 scale. The study does not fully fit in with O'Connell 's paper, while researcher Dubois is studying how to reduce obesity rates in low-income groups. But O'Connell believes that the study's proposal that "people who want to be successful should first behave like successful people in all respects" is consistent with his own view.
