Sky-diving? Bungee-jumping? If you're looking for a thrilling and simultaneously frightening experience, here's an activity you should consider: starting your own company.

Or, if you're looking to up the ante even further, start your own company knowing nothing.

If it makes you feel any better, just know you'll be following in the footsteps of self-made billionaire businessman and entrepreneur Phil Knight, co-founder of Nike, Inc. Sitting at a worth of about $100 billion, Nike currently boasts revenues of approximately $34 billion a year, 74,000 employees, and a globally famous brand.

In an interview to promote his book Shoe Dog: A Memoir by the Creator or Nike, Knight sits with David Rubinstein, who explains just how much experience Knight had when first starting the company in 1962: "You knew nothing about shoe design, you didn't know a lot about management, and," Rubinstein details, "you didn't have any money."

Despite this lack of knowledge and experience, Knight did admit a few key details about Nike's beginnings and how the company was allowed to soar. "We took advantage of the running boom, which became the jogging boom, which became the fitness boom...and we've benefited from all of that." Knight and his team's ability to evaluate, assess, and accommodate market demand helped make up for a perceived lack of business and design expertise.

When asked about what skill Knight was able to bring to the table despite knowing nothing, the Nike co-founder responds, "If there's one thing, I've been pretty good at evaluating people." Knight's exceptional people skills helped him not only succeed with Nike's early partners, his fellow employees, and his team mates, but his skill set also brought him to a greater understanding of the consumers who would be buying his shoes.

Above all, Knight carried with him an incredible love and passion for Nike. When explaining the meaning behind his book's title, Knight gave away how his passion fueled what he did. "A shoe dog is somebody that really loves shoes, and that was me. I was a runner...that became important to me and it's been with me ever since."

Starting your own company can be daunting, especially if you feel like you're not readily equipped with all that you need. Perhaps, however, it may be a good move to get started--to take your business idea and just run with it.

Or, as Knight would say: Just Do It.
