First jobs of CEOs

Interesting slide show on CNBC.com about the first job of a dozen CEOs.  None of them started in a corner office.  Occupations mentioned multiple times in the future include newspaper delivery (T. Boone Pickens, Michael Morris) and restaurant work (Michael Dell, Clarence Otis, Jr.).  The CEOs speak of these earliest jobs as important learning experiences:

• Doug McMillan, Walmart: “Teamwork wins and hard work pays off,” he said. “If you don't take care of the basics like showing up on time and striving to exceed the expectations of your leadership, your career doesn't move.”
• T. Boone Pickens, BP Capital Management said that trying to collect from customers who didn’t want to pay him taught him a valuable lesson. “You have to be persistent if you want to achieve your goals. You never know what the job you’re doing each day will lead to, so you have to put your all into everything you do,” Pickens says.
• Clarence Otis, Jr., Darden Restaurants said that serving a large number of people from all walks of life taught him how to approach every situation with a fresh attitude and a positive mindset.
• Jack Schuessler, Wendy's: “If you don't show up, you won't get paid!”
