Happiness is a measure that reflects the success with which people achieve their personal objectives of living levels, happy and healthy families and satisfying work.

GDP and GNP shouldn't be scrapped, they're of value, but they don't even give us an indication of economic well-being let alone individual well-being

They talk about Steve Jobs having a reality distortion field…. but all the entrepreneurs I met who achieved great things had that. They all had a wilful denial of reality… against all evidence to the contrary they had to believe they would succeed.. that's ultimately what entrepreneurs do.

Genius is (possibly) the presence of more- or more closely packed- neurons. I once held a chunk of Einstein's brain, the scientist who was dissecting and analysing it told me the neurons were closer together. We don't really know if that makes thinking faster… but when I sit with true brilliant people and watch them have conversations, they seem to have the ability to recall important bits of information, put the puzzles together, and see patterns faster.

Don't make the mistake of confusing net worth and self-worth.

On one hand, competitive high-pressure jobs lead executives into many situations that can induce worry and fear (anxiety), hopelessness and despair (depression), and urgency (stress). On the other hand, some people are drawn to high pressure jobs by their adventurous personalities, their ability to tolerate risk, and their motivation for achievement.

They took a relative view of risk… They had an understanding of the risks of something going wrong, but balanced that against missing an opportunity. When that opportunity exceeded the risk of going wrong? That's when they jumped…

Entrepreneurship means a constant willingness to keep learning. It's about maintaining that start-up spirit—where you're forever young, and forever in crisis. It's about always having your mind on the business: Lying in bed and constantly asking yourself, What should I do?

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.
