"Most important of all, as I said, is marketing," he added.
"Mike Markkula (Apple's second CEO) came in and he started teaching us marketing principles. He would teach Steve Jobs, who was just a young 21-year-old, principles of design and speaking to the press and what you say and how you describe computers and Steve became the excellent marketer of our big, successful product: the Apple II."
According to Wozniak, the best engineers have the right aptitude, not necessarily the best grades.
"The engineering isn't necessarily grades in college," he explained. "Find someone who has been building things in their little home or their garage all their life."
Wozniak is best known for designing the hardware, circuit board and operating system of Apple's first product, the Apple I, and leading the design on the Apple II.
