I do feel that there is less hope now than there has ever been during my lifetime and- it would appear- for centuries. When you speak to most young people, they don't have an articulate sense of the future, of what they're looking forward to.

You can't get addicted to drugs unless you're exposed to them. You have to be exposed in situation where you can determine the dose. If you take the drug long enough and in a high-enough dose… most drugs which are addictive, will give you withdrawal symptom… making you feel rotten, and giving you another reason to take more.

A lot of people assume that I would choose not to have bipolar disorder; but I'm grateful for it. I wouldn't trade it for anything in the world, because I feel like all the ups and downs have formed who I am, and made be braver, tougher… more creative and more capable.

I believe businesses need to move away from having profit as their primary reason for existing. Profit primacy can be replaced by mission primacy.

Studies estimate that climate change directly contributes to the death of over 400,000 people a year, and costs the world economy over $1.2 trillion per-annum. If we factor in man-made environmental pollution alongside climate-change, over 4.5 million people each year die as a direct result of man's impact on this planet.

I have not been an urban investor in re-gentrification, which tries to change the character of a community and, candidly, is very speculative. Instead I look at revitalisation, which constitutes investing in existing densely populated and ethnically diverse communities and delivering the goods and services that are sought after but not provided.

Research shows that empowering women to gain financial independence generates lasting impact, with women typically investing 90% of their income back into their families. In addition to this, McKinsey estimates that if women and men were to play an identical role in labour markets across the world, an extra $28 trillion would be added to the global economy by 2025.

I learned more from the people at those events – the community, the customer – than anyone in business.

Fear is healthy, fear is natural, and if anyone's ever told you they've been to combat and were never afraid... they're either lying or a sociopath. Fear is a very good reaction; it makes you think more clearly.

There is a naïve form which doesn't recognise the bubble, and thinks that real-estate will go up forever. There is then a second order overconfidence where someone recognises a bubble but feels they will escape it when other people don't.

At the beginning I literally started a business out of passion. I loved fitness- it changed my life- it changed my schooling, education and taught me skills that changed my life for the better. I just wanted to be in fitness. When we started the business- whilst the first 6 months were difficult- it started to gain momentum and started to feel like a real opportunity. That's when I had to grab the business by the 'scruff of the neck' and drag it to where I thought it needed to be.

Only a handful of diplomats and governments are prepared to put the global good before the national interest. Seldom is it the case for any diplomat that they put the global good high up on the agenda; in my career I've seen it very rarely.
