The oil tycoon was John Rockefeller. John Rockefeller was born into a civilian family. When he was 14 years old, he set two goals: one was to become a billionaire when he grew up, and the other was to live to be a hundred years old. Rockefeller died on May 23, 1937, at the age of 98. His second goal can be said to have been largely achieved. And his wealth extends far beyond that first goal. It is estimated that Rockefeller's personal wealth is no less than 1.4 billion, making him the first billionaire in American history.

Oil Tycoon’s Early Life

In 1855, at the age of 16, Rockefeller decided to drop out and study in the business world to make a living. He first went to the business school in Cleveland, Ohio, where he studied nearly four "tycoons"—— Rockefeller kept going to interviews but was rejected again and again. He persisted like this for six weeks, and even went to some companies two or three times. His hard work paid off, and Rockefeller finally got a job in a grain business. I became an accounting clerk with a monthly salary of US$12.
