"It's OK to have your eggs in one basket as long as you control what happens to that basket."

"I don't think it's a good idea to plan to sell a company."

"It is a mistake to hire huge numbers of people to get a complicated job done. Numbers will never compensate for talent in getting the right answer (two people who don't know something are no better than one), will tend to slow down progress, and will make the task incredibly expensive."

"A company is a group organized to create a product or service, and it is only as good as its people and how excited they are about creating. I do want to recognize a ton of super-talented people. I just happen to be the face of the companies."

"People work better when they know what the goal is and why. It is important that people look forward to coming to work in the morning and enjoy working."

"I don't spend my time pontificating about high-concept things; I spend my time solving engineering and manufacturing problems."

"I always invest my own money in the companies that I create. I don't believe in the whole thing of just using other people's money. I don't think that's right. I'm not going to ask other people to invest in something if I'm not prepared to do so myself."

"I don't create companies for the sake of creating companies, but to get things done."

"I don't believe in process. In fact, when I interview a potential employee and he or she says that 'it's all about the process,' I see that as a bad sign.

"I've actually not read any books on time management."

"I'm interested in things that change the world or that affect the future and wondrous, new technology where you see it, and you're like, 'Wow, how did that even happen? How is that possible?'"

"What makes innovative thinking happen?... I think it's really a mindset. You have to decide."

"People should pursue what they're passionate about. That will make them happier than pretty much anything else."

"Being an entrepreneur is like eating glass and staring into the abyss of death."

"I wouldn't say I have a lack of fear. In fact, I'd like my fear emotion to be less because it's very distracting and fries my nervous system."

"When Henry Ford made cheap, reliable cars, people said, 'Nah, what's wrong with a horse?' That was a huge bet he made, and it worked."

"When somebody has a breakthrough innovation, it is rarely one little thing. Very rarely, is it one little thing. It's usually a whole bunch of things that collectively amount to a huge innovation."
