Self-made millionaires are individuals who have accumulated their wealth through their own efforts, rather than inheriting it. They often start with limited resources and leverage their skills, creativity, and determination to build successful businesses or investments. Many self-made millionaires are known for their entrepreneurial spirit and willingness to take risks. These individuals come from diverse backgrounds and industries, including technology, real estate, and entertainment. Notable examples include Elon Musk, who founded companies like Tesla and SpaceX, and Oprah Winfrey, who built a media empire from humble beginnings. Their stories often inspire others to pursue their own financial goals.
