I would describe games as an art form centred around systems. Viewing the world as a system means perceiving it as a collection of interconnected elements. These elements interact in a way that both enables and restricts themselves and each other. Essentially, what is observed is the collective behaviour of these elements as they unfold over time, creating a range of possibilities.

I believe that success in business can be measured by if you enjoy what you are doing; create something that stands out; create something that everyone is really proud of.

Entrepreneurs have to focus on how a business makes money and focus on that rather than the expense side of the business. That also allows you to start quicker and instead of deferring your idea, you could get to market in 30 days.

All you have to do is walk through an airport, for example, and notice that it is very difficult to navigate through it. You will encounter humans (almost statue like) who are glued – looking at their mobile phones, unaware of what is happening around them, because they are addicted to their technology. That is by design that people are addicted to technology.

We are the first generation that through its neglect could destroy the relationship between humans and the planet, and perhaps the last generation that can prevent dangerous climate change.

Once one understands the disadvantage of being at the bottom of the stack, it becomes much easier to understand the importance of speed in HFT. As new price levels form, HFTs compete with other HFTs to join the new price as quickly as possible in order to secure advantageous stack position for passive orders.

Research has shown that learning brings more joy than material rewards. In a study where participants were given money for doing well on a task, they felt happiest not when they received the money, but when they learned something new about the task.

A refugee, we might say, is a person fleeing life-threatening conditions. In daily parlance and for journalist purposes this is roughly the meaning of refugeehood. Predictably, in legal and political circles, among those officials who formulate refugee policies for states and international agencies, the meaning is considerably more circumscribed.

Surgery, like many other disciplines, is primarily about facts, your relationship with the facts, how you manage, handle, interpret and use those facts. This is something we all begin to do very early in life, in our childhood. We look at information coming in from the external world, determine what is useful, determine how we understand it, build a fuller picture and effect change. A surgical mindset is very much that.

One thing that really helped us was NOT following the IMF prescription, and hence I think the fact that we insisted on having growth (alongside stability) was something that made for a big change in Brazil.

If only one-quarter melted, it would lead to a 2-metre rise in sea-levels all over the world and would threaten thousands of cities and towns on every continent.

Like everyone, investors get hurt by the implicit loss of purchasing power of each dollar inflation implies. However that is only the tip of the iceberg, as this loss is likely to be compounded by the tendency for traditional investments to suffer additional erosion.
