The biggest of all perhaps is how life began. We still don't know how life started from a soup of chemicals – how molecules assembled, replicated, and managed to survive and evolve into incredibly complex life forms. We also don't know how likely this was, and if we ever able to answer that, it will give us a better idea of whether we're alone in the universe.

The people who do better are somehow better connected. In other words, there is an inherent logic in the idea that the more connections individuals make within their communities the better off they will be emotionally, socially, physically and economically.

The ability for hedge funds and other private investment product to advertise is certainly a big deal that will have lasting impact on the manner which these products are distributed and marketed.

A brand has to be authentic and be born of a personal passion. If you, its creator, doesn't want the product, no one else will. If you want it, chances are it will be wanted around the world. Desires are universal and speak in every language.

We are definitely seeing a shift in the skillsets that are needed. On our platform here at Udemy, we are seeing a lot more people taking courses around empathy and emotional intelligence and coaching. How do you ask the right questions? How do you enquire? How do you actively listen?

Generally speaking, I advocate for entrepreneurship as being originating something entirely new – taking it from zero to one, so to speak. This endeavour doesn't strictly have to be a technical startup or a monumental success. The main focus is on initiating something on your own, which essentially leads you into the journey of entrepreneurship. It's a voyage that can be challenging and intricate, marked by a series of failures. Moreover, it's a path that you'll often tread alone.

The sad reality is that if we tried to pass that declaration today, the UN General Assembly would fail to do so. Firstly, we don't have someone like Eleanor Roosevelt as an advocate for human rights, and where previously the US played a leadership role, Trump would no doubt block virtually every human rights pillar associated with the declaration.

I think you're going to see impact models that challenge many of our incumbent industries. The most vulnerable in our society are currently overcharged because the system assumes, they are higher-risk, and so those in our society who are least able to afford charges, are being charged huge overdraft and borrowing rates.

We must stand up and say that a business model based on secretly tracking us in order to find, and exploit, weaknesses in our attention is not acceptable. It's immoral.

I often hear people say that everything that matters must be measured, and if it can't be measured, it doesn't matter. I believe the absolute reverse. Nothing that matters can be measured.

The original motivation was to develop a sense of what lending rates were among the large money-centre banks. It was really meant as a reference rate of where supply and demand of funds sat at a given point in time. It was meant to be a fairly robust measure of borrowing and lending activity.

Courage is not the opposite of fear, rather it is the triumph over fear. There is nothing courageous about a guaranteed outcome, right? Courage is being yourself in a world where everyone tries to be like everyone else.
