A Lesson in Business, Steve Jobs Style (QUOTES)

The Wizard of One Infinite Loop, Steve Jobs, has stepped down from his post as chief executive officer of Apple.

The move comes as Jobs' health could be in serious jeopardy. The long-time CEO, who co-founded Apple in 1976, was diagnosed with pancreatic cancer in 2003. He treated the cancer and apparently was fine until 2009, when he had to take a leave of absence because his health issues were more complex than originally thought.

In 2009, he had a successful liver transplant and returned to work in June of that year. All appeared to be fine until January of this year when once again took a leave of absence leaving Tim Cook, Apple's chief operating officer in charge.

In his most recent appearances, including at June's Worldwide Developer Conference, Jobs looked thinner and less healthy than he had in previous years. Naturally, Jobs nor anyone involved with Apple will comment on his health, leaving everything up to speculation.

Jobs' impact is obvious. Behind his vision, Apple has become the biggest company in the world (market capitalization wise) and probably one of the most influential. He's helped create and develop the smartphone and tablet categories and reinvented the PC with his Mac lineup. He also helped launch Pixar, the successful animated film company.

Jobs own personal worth is $8.3 billion. He is one of the most famous CEOs of the past 30 years. His Apple Co-Founder Steve Wozniak said it best:

Steve Jobs is the greatest business leader of our time. He'll be remembered for 100 years. To think that I knew somebody who became the most important person in the world. It's actually -- it's kind of stunning, said Wozniak.

Over the years, Jobs has been known to give insightful quips via press conferences and interviews. Here are a few of his most memorable ones.

A lot of companies have chosen to downsize, and maybe that was the right thing for them. We chose a different path. Our belief was that if we kept putting great products in front of customers, they would continue to open their wallets.

Be a yardstick of quality. Some people aren't used to an environment where excellence is expected.

Design is not just what it looks like and feels like. Design is how it works.

Innovation distinguishes between a leader and a follower.

I want to put a ding in the universe.

Sometimes when you innovate, you make mistakes. It is best to admit them quickly, and get on with improving your other innovations.

You can't just ask customers what they want and then try to give that to them. By the time you get it built, they'll want something new.
