There's No Such Thing as "Just"

When talking to clients, be they students of individuals in corporate America, I often hear "I'm just and admin" or "I'm just a waiter".  

What's with the just? 

My question - what skills does it take to be a great admin or waiter?  
     Strong organizational, communications and interpersonal skills.  
     The ability to think on your feet and deal with difficult people and situations.  

What are some of the most difficult things you had to do to be a great admin or waiter?  
     Juggle multiple tasks, client needs at the same time.
     Prioritize.
     Deal with people who are angry or totally unreasonable yet bring the situation to a happy end.

So there is no such thing as just!  Every job requires skills and you need to own them and be proud of yourself in order to present with confidence!
