It was not wealth or fame that these people wanted… These individuals had, in their own minds, observed a particular customer need that wasn't being met. They were wired in such a way, that this need seemed obvious to them. Whether it led to a million or a billion? That was secondary.

These individuals were extremely well-read, very curious and very disciplined… In a world where so many of us multi-task, when we met with these individuals, they were very focussed on the interview, free of interruptions. That's very unusual nowadays.

Inventors shouldn't be afraid to take risks. They should embrace failure and learn from their mistakes. I created 5,127 prototypes of the first Dyson bag-less vacuum cleaner and only the last one was right! Not being afraid to fail is something I think all successful entrepreneurs have in common.

I have learnt that situations in themselves are not inherently stressful. Our perception of situations is what creates stress for us. Some players thrive in the biggest sporting occasions and others struggle to cope.

As humans we need to evolve constantly because the behaviours that got us to a certain level won't suffice to even maintain this level let alone to take us to the next. If this sense of growth and contribution isn't experienced in our lives, difficulties will arise.

We often project our 'superhero' aspirations onto our leaders and vulnerability, and other more human traits, are not always encouraged. Organisational leaders often experience loneliness, and the 'truth' within their company is often illusive to them because subordinates will often tell them what they want to hear.

You can never convince a chimpanzee to give you a banana by promising him that after he dies, he will go to chimpanzee Heaven, and there receive countless bananas for his good deeds. No chimpanzee will ever believe that. Only humans believe such stories. This is why we rule the world, whereas the chimpanzees are locked up in zoos and research laboratories.

Humans began to create and believe things that exist only in their own imagination. Things such as gods, nations, money and human rights. This enabled humans to start cooperating on an unprecedented scale.

It's difficult to describe to people who aren't curious, just what curiosity is. Imagine explaining to a robot or a computer what curiosity is! For those of us who experience it however, it's almost a primal-pull.

The change I'm most passionate about – because of the impact it's had on my own life – is creating a healthy transition to sleep that begins before you even step into your bedroom. I treat my own transition to sleep as a sacrosanct ritual. First, I turn off all my electronic devices and gently escort them out of my bedroom.

My own life has improved in pretty much every way. These days, 95 percent of the time I get eight hours of sleep a night. Now, instead of waking up to the sense that I have to trudge through activities, I wake up feeling joyful about the day's possibilities. And I'm also better able to recognize red flags and rebound from setbacks. It's like being dialed into a different channel that has less static.

Great entrepreneurs are people with tremendous passion. Without passion you cannot go on a journey that requires such huge personal sacrifices, looks bleak, risky and impossible in the beginning…

Just before my father passed away, the company had grown considerably. He said to me, 'I have six children, and who would have believed that you, Frederik, out of all my children would have been the one that succeeded!' I'm not sure that was a compliment!

Today, entrepreneurship is fashionable, it's something you can develop in your character and strengthen. I'm not so sure… I believe that entrepreneurship is something you're born with, or not. I've met many highly intelligent, and incredibly bright people who have not been able to develop their ideas into sensible businesses. Entrepreneurship is not related to intelligence, it's something you have or don't have.

I'd had 20 years of the most indescribable intensity and focus; and not many people can appreciate what that means, because there are very few people that have grown a business organically from one person to over 10,000. After 20 years of that, I had sort-of 'had enough.'

In line with most highly-tuned talents, I absolutely believe that entrepreneurship is a genetic gift that you're born with. What you do with that gift depends on your upbringing, opportunities and inspirations; you either make them massively better or neglect them. That combination of genetics and sheer hard work is the 'secret' of getting to the top.
