One famous example is Steve Jobs. He was ousted from Apple, which was a huge failure at that time. But then he came back and revolutionized the company with products like the iPhone. Another is Colonel Sanders. His fried chicken recipe was rejected many times before KFC became a global success. And J.K. Rowling was a struggling single mother when she wrote the first 'Harry Potter' book. It was rejected by multiple publishers before it became a global phenomenon.
The story of Walt Disney is also among them. Disney faced multiple bankruptcies and setbacks in his early career. People didn't believe in his vision of creating a magical world of animation at first. But he persisted and now Disney is a huge entertainment empire. Thomas Edison failed numerous times before inventing the practical incandescent light bulb. His countless attempts showed that failure was just a step towards success. Oprah Winfrey also had a tough start. She came from a poor background and faced many obstacles in her career, but she overcame them all and became one of the most influential media personalities in the world.
Albert Einstein is an interesting case too. He had learning difficulties as a child and his early academic career wasn't smooth. However, his unique way of thinking led to the development of the theory of relativity, which completely changed the understanding of physics. Michael Jordan, often considered the greatest basketball player, was cut from his high school basketball team initially. This failure motivated him to work harder and he went on to have an extremely successful career. Bill Gates' first business, Traf - O - Data, was a failure. But he learned from it and went on to build Microsoft into one of the most powerful companies in the world.
