Your brain has an agenda: to make you feel good about you. So if you're the CEO, and you decided to launch a product two weeks ago, your brain assumes, 'Well, that must have been the right decision.' It starts scanning the environment for proof — cherry-picking anything that confirms you were right.

There's a pervasive sentiment that silence or a lack of immediate response equates to complicity, and this is seen as an endorsement of a particular viewpoint. These demands for instant opinions are concerning as they overlook the individuals who are earnestly seeking to grasp the full picture, delving into the nuances of age-old issues before formulating a stance.

Diseases of the heart are sometimes thought of as forgotten diseases, which is ironic as they still kill more people than any other condition on the planet… and are on the rise in some of the largest countries in the world like China, India, Pakistan and Indonesia.

You need to work like someone's trying to take it all away from you, because they are.

There was some fascinating research in Judaism which showed that as an individual moved from being orthodox, to conservative and eventually liberal.. there was a steep rise in the prevalence of drug use and drunkenness in society.

Ultimately, you have to fail at some stage with whatever you do, to get the successes that you need in the end.

We're not really creating a specific artefact—we're setting a direction for a process. There's no upper limit to that process; we're simply saying we'll create something capable of becoming smarter and smarter.

Four days before she died, she challenged my daughter and I to try and find a pocketful of happiness in each day, which has become the mantra by which we navigate the abyss of grief, following her death. I don't think you ever get over grief, you just have to find a way to accommodate and travel around it.

You don't have to choose a business that's going to drown you, be a treadmill, or suck you underneath. You can start slow, make a bit of money and then double down. You don't have to risk it all at the beginning. Start slow… make a bit of money… make a bit more… then you're playing with the house's money.

Water is the essence of life. On Earth it's used to grow plants and within industrial processes but in space it takes on a whole new form. We can use water as a radiation shield. One cubic metre of water gives the same protection as Earth's atmosphere and magnetosphere. Water is a molecule made of hydrogen and oxygen- and that happens to be rocket fuel.
