John Paul DeJoria – Paul Mitchell
John Paul Dejoria is one of the most inspiring individuals on this list. As a child, he spent time in foster care when his single mom could no longer care for him. In high school, a teacher told him that he would never succeed in anything. By his 20s he was so broke he had to collect soda cans and bottles for extra cash. In his late 30s, he lived out of his car. At age 37, he borrowed a few hundred dollars to start his own business when he teamed up with Paul Mitchell to create a hair care line. After Mitchell died relatively young of cancer, Dejoria continued leading the company. His net worth is now 2.6 billion. He is seen above with his wife.
