From Oprah Winfrey to Steve Jobs to J.K. Rowling, entrepreneurial success stories are the stuff from which American dreams are made. Much like these famous names, the six self-made millionaires we’re profiling have one thing in common: Thanks to hard work, determination and sound advice from mentors, friends and family, they’ve been able to build thriving businesses from the ground up.

The rise to the top can be bumpy. In fact, some of the entrepreneurs we talked to were homeless during the early years of their companies. That’s why they all agree that it’s important to help others in need. All, including Radio One’s Catherine L. Hughes and Life is good co-founder Bert Jacobs, give back to the community by volunteering time, donating to charitable organizations or running their own charities.

Learn how these six diverse entrepreneurs -- from a t-shirt designer to a media mogul -- turned meager beginnings into multimillion-dollar success and what advice they offer to budding business tycoons who hope to follow in their footsteps.
