The key to being successful in business is trust, you have to trust the people you work with. This trust must co-exist with competence. First and foremost the people in your business have to be extremely competent at what they do, and then it's up-to you as a leader to have trust in them.

Money can't solve many of the problems that truly plague people. It can't solve the problems in a relationship between a husband and wife, beyond the narrow economic front. It can't straighten out the relationships you have with your children—in fact, it can make them worse.

Risk is actually an asset. Fear isn't meant to be dismissed; it's intended to be embraced. Fear sharpens your focus, enhances your performance, and boosts your resilience. This is something many haven't realised—fear is a superpower meant to be embraced, not avoided.

Climate change isn't just warming the planet - it's fundamentally rewiring the hydrological cycle. Wet places are getting wetter, dry places drier, and the timing of water availability is becoming increasingly unpredictable.

One of the themes which is perhaps more important in the intellectual rather than practical world was the excessive love affair that people in the financial world had with the efficient markets hypothesis. If you take that literally, there can't be bubbles. Who can believe that now?

What people fail to recognise is that fear is different for everyone. Your emotions are unique to you and you've really, really got to take time to concentrate on yourself.

Status, I believe, is intrinsic to our very being it's at the core of who we are. This quest for status isn't a novel aspect of human behaviour—it's a pursuit that predates our very existence as humans. This pursuit isn't just a facet of our lives; it essentially narrates the story of human existence.

I believe that working towards women's economic empowerment at the global level is the single most important battle we will fight in our lifetime, and that's because harnessing the incredible talents and potential of women is not only the right thing to do – it will also create stronger economies and a fairer society for all.

Philanthropy is very much like business, there's not such a huge difference. In business you have a mission statement, in philanthropy you have a vision. I believe in philanthropy we want to do things that give back as much as we give, otherwise it doesn't have permanence.

Taking that first step is your biggest competitive advantage; most people won't do it.

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.

And the overall picture that's emerging is that the controls which still work operate more along corporate boundaries than along national boundaries. In order to censor YouTube, for example, countries like Turkey and Pakistan had to block access to the whole site; it's not practical just to block selected content.
