Rockefeller immediately put those insights to use. At twenty-five, a group of investors offered to invest approximately $500,000 at his direction if he could find the right oil wells in which to deploy the money. Grateful for the opportunity, Rockefeller set out to tour the nearby oil fields. A few days later, he shocked his backers by returning to Cleveland empty-handed, not having spent or invested a dollar of the funds. The opportunity didn't feel right to him at the time, no matter how excited the rest of the market was—so he refunded the money and stayed away from drilling.
