Back in 2008-2010, I did sales for Norwegian Cruise Line.  I wore a suit every day to work and spent the entire day making sales calls, with the goal of making 150+ calls per day.  It was my first real job after college and a short stint in professional baseball, and taught me a lot about sales, hard work, and navigating corporate culture.

Many of the lessons I learned in those 2 years at NCL have stuck with me to this day.  

I overcame my fear of selling, while learning how to listen to customers.  I learned that there is a lot of money and abundance in this world, and it isn't my job (especially in sales) to project my personal beliefs about money onto others.  I learned what it took to become a top performer, and that it's a lot easier to stay at the top then it is to ascend there.
