By age 25 John D. Rockefeller controlled one of the largest oil companies in America. By age 31 he had become the world’s largest oil producer. By age 38 he commanded 90% of the oil produced in the U.S. By the time of his retirement at age 58, he was the richest man in the country. By the time he died, he had become the richest man in the world.

But there was little in Rockefeller’s upbringing that would signal his great success. He was born in a run-down house in New York in 1839. His mother was a solid, religious woman, but his father, William Avery Rockefeller, was little more than a dishonest salesman, unable to provide for his family.

Young John grew up helping work the family farm. But he had his eyes set on greater things, and earnestly desired to rise in the world.

He had a talent for numbers, and he dropped out of high school to become better acquainted with their management. Enrolling in a 3-month business course at a commercial college, he learned the basics of book-keeping and banking.

After graduating at the age of 16, Rockefeller left his rural home to look for a job in Cleveland. As Rockefeller remembered, the job market was tight, and the response was not encouraging: “No one wanted a boy, and very few showed any interest in me.” Yet young John was not at all discouraged.

From morning until later afternoon, six days a week, for six weeks — sweating through Cleveland’s hot summer, walking its streets until his feet ached — Rockefeller continued to seek a job. He attacked this goal with patient persistence. Finally, on September 26, 1855, he heard the words he’d been waiting for: “We’ll give you a chance.” Ever after, Rockefeller referred to this date as “Job Day” and celebrated its anniversary with more passion than his own birthday, for this was the great turning point in his life. Through singular focus on a goal, and patient persistence, he had obtained a toehold in the world of business.
