When it comes to succeeding in business smart people understand karma is a thing to be taken seriously. In other words, sowing positivity into others may reap a harvest of connections, good words or otherwise tip the balance toward your good fortune.

That's according to Bobby Rossi, managing partner at restaurant group LDV Hospitality's No. 8 and Rec Room nightclubs, cofounder of the men's lifestyle website Headlines and Heroes and principle of Rossi Marketing Group. As someone who has been working in the nightlife and hospitality space for more than a decade, he sees all kinds of people--servers, bartenders, managers, DJs and other talent--moving through the industry while on their way to something else. Does it make sense to make friends with and support these transient folks? Absolutely, Rossi says. Here's why anyone working in business should build relationships with people at all levels of an organization, from the bathroom attendant all the way up the org chart. 

1. The positive energy you exude toward others will come back to you.

On some levels, it's a hospitality thing--people in the industry understand the value of making people feel comfortable. But being supportive and exhibiting happiness for the success of other people is something everyone should do. "The more you put out, the more you will receive in return," he says. "Displaying genuine happiness for others can only bring some of that happiness into your own soul and life, as well."

2. People who remember you as being positive will likely be your advocates someday.

Whether it's opening a door, making a connection or even just vouching for your character, the people with whom you've made a good impression will likely do whatever they can to help you.

3. Demonstrating happiness for others is refreshing.

People are remarkably head-down these days, constantly checking a phone or device. How does it make you feel when people stash their gear and ignore distractions to look you in the eye and pay attention to what you're saying? Be that person, live in the moment and react positively to what the person in front of you is saying.  "The display of true happiness towards someone shows that there is still the ability to be present," he says.

4. Haters don't understand the kind of effort it takes to succeed.

Don't be the kind of person who envies an "overnight success." Such a thing does not exist. In fact, most success stories involve at least a decade of hard work that outsiders don't appreciate. "[Haters] don't put forth the same level of effort or work into their own endeavors and therefore do not achieve the same success as the people who do," he says. "It results in an emotion of negativity as opposed to being genuinely happy for somebody and maybe learning from their success and applying it to their own goals."
