I noticed trolling because I was a troll when I was a teenager. I was one of those guys who spent a lot of time on forums at the weekend – trolling people. Back then, it was more like pranking; sending people a dud-link that would send them to a weird cartoon or porn site.

The physical and mental aspects of our lives are inseparable and taking care of the basic physical requirements is essential. Athletes and leaders rarely experience deep relaxation and this can become transformative in their lives.

I found myself deeply entrenched in the political world because, as I've come to realize, decisions about our bodies aren't made in clinics or doctor's offices. They're made in Westminster.

As an entrepreneur you have to know your market. You shouldn't take too much advice, and you need to believe in your own ability and be ready to tackle problems. You also have to be prepared for the fact that it may not work!

I don't see things as impossible; I got right to the equations to figure out how this could be achieved; I didn't put a barrier on my mind or body. A practitioner is the person who goes out and breaks the limits of the mind, the soul, the body.

At the level of individuals, teams, or even firms, knowledge grows and then saturates. It has a finite 'carrying capacity.' What is interesting is that while these individual units are finite, society at large looks infinite because of changes in the teams—the incumbents—that perform best.

In our market-economy, consumers have the power. I also believe that almost every consumer has an element of compassion in herself or himself.

If someone consistently films artillery strikes from their home, not only can we geolocate where the strikes are occurring, but we can also pinpoint the filmer's residence. If an unfriendly state actor would rather not have such footage made public, they could easily direct their artillery towards the identified filming location. This situation underscores the importance of witness protection.

You cannot say you support a values based human rights agenda and have your defense industry dictate the terms of your relationships between states to the extent that you won't criticize states who you sell weapons to. People see this for what it is, they recognise the internal and external inconsistencies and are tired of it.

Despite being an immediate part of our existence, consciousness is potentially the most complex and elusive aspect of the universe. We haven't even begun to formulate the right questions to unravel its intricacies.

You don't need to be a celebrity to suffer from what social media does to you; it's happening to everyone. For me, I have to find a routine and discipline with how I use my public image.

Endurance is mind over body. It's about tapping into something within us that allows us to push further than we ever thought possible, especially at our weakest moments.
