Want to know who the most important person is in your business?  Well I guess it depends on who you ask ; ).  But I'll give you my opinion.  It's not the CEO or the CFO or the crazy smart data scientist.  Of course those are very important roles.  But the MOST important person in your business, IMHO, is the person who interacts with your customer.  And much of the time, that's far from the highest paid person on the payroll.  

Check this out:  To open a McDonalds franchise and pay the first 90 days of expenses costs between $500k and $2,500,000 depending on the city.  Do you know how much a McD's customer cares about that?  (none)  So after you've literally invested millions of dollars just to be in business, your first customer walks in.  The big question is whether they will be served by a clean, polite, cheerful, professional or by someone who acts like working there was a condition of their parole.  Your customer's first experience is huge and you get to decide who that customer interacts with.  

If you own a service business, who will your potential or existing customers be served by on the phone?  Do they have a cheerful voice or a "what now?" voice?  If you own a medical practice, will your customer be greeted by someone at the desk that seems happy when your patients, who likely aren't at their best anyhow, walk into your office after you've spent a decade in college just to be in practice?  

You get the picture.  To me, the front-line person in your business is the face and voice of your business.  The front-line person is one of the most influential team members in the company.  Choose wisely.  Don't overlook irritable tones, impatient nonverbal communication or emails that bite for no reason.  You've worked too hard to get here.  Double down and hire a person that truly represents your heart and purpose, and your customers will thank you.
