For the first time in over 20 years, I feel brown… I find myself being extra careful in terms of how I dress, where I go, how I speak, what I carry and how I behave; not to conform to any new social norms- but rather, so that people don't mistake me for a terrorist.

Any time you're in a situation where the price is 'too low'—and I put that in quotes because it might not feel low to you, sometimes things are very expensive, but there are more people who'd like to buy the thing than they have the ability to serve—that's when a hidden market will crop up.

Everyone needs encouragement and everyone needs hope. I have an open policy with my foundation insofar as I don't put restrictions on who can come to my camps – I want anyone who needs it, to have access.

One of the simplest but hardest things to do is to be honest with ourselves. We are works-in-progress from the day we're born, till the day we die. You should never, ever, stop working on yourself.

For over 40 years however, we've fostered trade and investment relationships because we're in the EU. A lot of investment has flowed into the UK because we're in the EU; Nissan in the North-East, Toyota in the Midlands and other prospective investors such as Hitachi.

A particular individual trait that has piqued my interest through research is intellectual humility. Embracing the possibility of being wrong enhances the likelihood of being right—a somewhat magical paradox.

When you fail, you take ownership of the failure, and then you assess what mistakes were made, what could be done differently, what better instructions you could have given, what better support you could have given, then you fix those problems, move on and try again, simple.

It's like a tripod. Without one of the three, the whole marketing strategy collapses.

Ultimately, there are no values in the secular world that can replace the complete happiness people find in the vision of the face of God.

Diamonds are a miracle of nature, they are millions of years old, they survived a hazardous journey to the earth's surface and the discovery of them is an exciting moment. To see the rough diamond and then watch it come to life on the polisher's wheel with incredible fire and scintillation is incredibly inspiring.

Negotiation is really a life skill, and it's essential in this day and age.
