Consciousness is the most troubling because it's so hard to deny its existence. With all these other tricky, troubling phenomena, it's at least an option to say maybe it doesn't exist, maybe we're not really free in the way we think we are. But with consciousness, it seems hard to make sense of the idea that nobody's ever felt pain. Nobody's ever seen colour.

It's becoming increasingly clear that we don't yet know how simple an organism can be and still be conscious. There's now quite good evidence that bees not only learn tasks but can watch another bee perform one and then learn it themselves. Twenty or twenty-five years ago, no one would have believed that possible.

Being an entrepreneur is no harder than working for someone else; it's simply a different experience. I completely agree that the whole narrative of entrepreneurship being excessively hard is exaggerated and fundamentally untrue.

When you're involved in conflict, you're not sane. You may start out being sane, and in those early stages it's certainly possible to mediate and arbitrate. Using those tools you often end up cutting the baby in half – you give a little, I give a little, you give a little more, I give a little more, and suddenly everyone is miserable.

When I sense stress, I allot three minutes to fully immerse myself in it. Many individuals attempt to escape stress, but evasion often amplifies it. It's akin to instructing someone not to think of pink elephants; the very command makes it impossible not to.
