It is no secret that the economy is a little unpredictable right now. With changing markets in a changing world, it is important that everyone prepare for the future and retirement—even if it still seems like light-years away.

Job interviews can be daunting—especially if your prospective employer wants to chat face-to-face online. In recent years, online job interviews have become more popular and many companies, including Hilton, are regularly using technology to conduct preliminary interviews.

Whether you’re applying for an internship or preparing for your future career, it is important to have a polished résumé that speaks to your character and skill set. As a Career Counselor at Johnson & Wales University’s Denver Campus and an online instructor, I frequently review student résumés.

1.  Be on time.

In my life, I have performed with the Florida Symphony, the Oakland California Symphony, the Boston Pops Orchestra, and was an associate member of the Chicago Symphony.

In a way, music is a lot like business, and during my transition from full-time musician to full-time business executive and consultant, I noticed a few parallels.

What does country singing sensation Carrie Underwood have in common with the newest generation entering the workforce?

She’s a millennial—and she has a keen sense of this generation’s definition of success: “Successful people have a social responsibility to make the world a better place and not just take from it.“

At one of my first jobs, I had the opportunity to undertake my first true professional development experience. I was in sales, and my supervisor wanted me to take a Dale Carnegie Training course.

Last summer, I had the opportunity to attend a conference. In terms of my normal professional career, this statement is not particularly significant, however, this conference was different because it wasn’t actually for me. My wife, who is a stay-at-home-mom, decided to sign up to be a retailer for a direct sales company.

What’s the biggest mistake you’ve ever made at work?

If you can bear it, close your eyes and bring yourself back to that moment … you know, the one right before you hid under your desk and hoped everyone would just think that you went home early because you were sick. Forever.
