Elon Musk
He spent two years at the Queen's School of Business in Kingston, Ontario. He moved to the University of Pennsylvania where he earned a bachelor's degree in economics from the Wharton School. He stayed a year to finish his second bachelor's degree in physics. Then he moved to California to attempt to get a PhD in applied physics at Stanford but he left the program after only two days because he wanted to pursue his entrepreneurial aspirations.
