Doug McMillon, Wal-Mart

Doug McMillon is the president and CEO of Wal-Mart Stores, Inc. Wal-Mart was his first employer, and they’ve remained his one and only ever since he started working at their Arkansas warehouse at age 17 for $6 an hour.

Today, McMillon sits high atop Wal-Mart’s corporate ladder. However, he claims that he learned skills at his first job that he still applies today at the highest level of power.

“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.”
