What if certain words could open doors for you and win over your coworkers and others in the workplace? Turns out, they can.

Don't believe me? Take it from John Mackey, co-Founder and co-CEO of Whole Foods Market. According to Mackey, these three remarkably powerful words can open doors and help you find true success and happiness.

1. Purpose

In many people's minds, the word purpose is closely associated with the word goal. If people don't know the function of the business, how could they meaningfully work for it? As Mackey better puts it, "I think the most important thing for a business is to discover what is its higher purpose." Once you establish what the higher purpose is, it's easy to enjoy working at the business--so much so that it turns into a success. "You find joy there. You find happiness and you know you are on the right track," Mackey says.

2. Love

While it may seem like the most overrated of words, Mackey stresses how important it actually is in the business world. "We need to build enterprises based on love. Love needs to come out of the corporate closet," he writes. Many leaders and employees alike feel that they can build entire businesses from the ground up by ruling with an iron fist. Yet, few realize how much more effective it may be to actually govern with a loving hand. People are typically much more receptive to kind words than cruel ones, after all. Mackey points out that "We can't transform an enterprise without releasing love in it."

3. Integrity

Honesty, as well as the ability to give your word and stick to it, is a rare quality to find these days. "People routinely lie. They don't have the courage to do the ethically right thing," Mackey says. The consistency that comes with someone you can count on is invaluable in our dynamic environment. Mackey articulately explains the reason for the constant lies we receive. He writes, "Corporate leaders spin things because they don't think we can handle the truth. So, we've got to start handling the truth. Integrity is very important: purpose, love, and integrity."
