Sure, everyone knows what a brand is. Coke, Pepsi, McDonald's. But that buzzword is getting thrown around a whole lot in career and job search conversations these days, too. And you might be thinking to yourself, "why do I really have to care about this?"

Here's why: Whether you're on the job hunt, a student, or gainfully employed, you must think, act, and plan like a business leader. With the surge of social media, you have not only the ability, but you now have the need to manage your own reputation, both online and in real life.

Employers will Google you before they even invite you to an interview. (Your current employer probably has an eye on what you're doing, too.) And when you interact with people, both online and offline, they'll build up an image of who you are over time.

And here's where you come in: You want to be in control of all of those impressions. Why leave your professional reputation to chance, when you can be your own PR guru and manage your image?

Your personal brand is all about who you are and what you want to be known for. And while that's a pretty broad concept, I'm going to break down the process for building your brand into a few easy steps, which we'll cover over the next few weeks.

Your first task: Developing your "brand mantra." Basically, this is the "heart and soul" of your brand, according to branding expert Kevin Keller. It's the foundation of all of your branding efforts.

It's not a mission statement (check out Guy Kawasaki's blog post for the difference)-rather, it's a quick, simple, and memorable statement describing who you are and what you have to offer. Ivanka Trump is "an American wife, mother, and entrepreneur." FedEx is "peace of mind." Disney is "fun family entertainment." Rick Ross feat. T-Pain is "I'm a BOSS."

And yes, those are all famous options, but the same basic principles apply for your own brand. Ready for your turn? Here are four simple steps to creating your mantra:

1. Determine Your Emotional Appeal

For starters, think broadly about your personality and how it affects the experience someone will have with you. Are you insanely organized? Do people love working with you for your killer sense of humor?

Make a list of words that best describe these features of your personality. These words are known as emotional modifiers. Hint: They can be as simple as Disney's "fun."

Questions to Consider:

• How do I make people feel?
• How do people benefit by working with me?
• What words do others use to describe me?

2. Determine Your Description

Your next step is coming up with a descriptive modifier that brings clarity to the emotional modifier, identifying what or who your brand is for. In Disney's case, it's "family." In Nike's mantra, "authentic athletic performance," "authentic" is the emotional appeal, while "athletic" tells you what the brand is for. As an individual, yours might be an industry ("healthcare" or "education"), or it might be a tangible skill ("creative" or "strategic").

Questions to Consider:

• What field or industry am I in (or do I want to be in)?
• What are the words I would use to describe my work?
• Who is my target audience?
