The iron in the haemoglobin in your blood was cooked up in the heart of a massive star that blew up about 8 billion years ago. We understand now in pretty good detail, how intimately connected we are with the cosmos.

I wasn't just fighting for myself. I was fighting for an entire country and millions of fans around the world who believe in me. That is why I will always give 100% in and out of the ring.

You know those people starving in Africa? Pretty soon, they are going to be able to call us… to complain. There are people who are likely to have cheap access to reliable International phone calls before they have cheap access to a reliable food supply. That's a remarkable thing to contemplate.

Stay undefined and stay curious. Our world is changing so rapidly that the only way to survive, thrive and adjust is to have a deep and constant level of curiosity.

Comedy chips at people in power, particularly those who use tyrannical power. It strips their fake respect, and destroys the fake fear they create; and these are people who rely on being respected, and being feared. Comedy and satire make the emperor look naked.

Music is woven into the fabric of the universe. As far back as Pythagoras and Kepler, scientists were writing about the fact that music was intrinsic in the planets… part of the harmonic series in sound. We also have a whole branch of knowledge called zoomusicology, which shows that an appreciation of music and sound is a part of nature, not just unique to humans.

A lot of businesses these days are markets. Companies like Google make markets for advertisements, Amazon is a market in and of its own right. Uber, AirBnB and many more are becoming big businesses by creating markets.

Our vision is something we call 'SETI of the mind.' The goal is to treat the DMT space and other altered states as novel domains to be explored, much in the same way we treat outer space. It is a completely new frontier inhabited by beings that we treat as potential intelligences with whom we can establish a two-way relationship.

Without their encouragement though, I don't think I ever would have had the confidence in myself to even pick up the pen. That one small bit of encouragement had such a huge impact on my life. It made me realize how sometimes it really is the little stuff that's most important, and we never know how significant our encouragement can be in someone else's life.

By 1970, with a budding awareness of computers, I envisioned a future where the cumbersome administrative tasks of gaming could be offloaded to computers, transforming gameplay into something as visually captivating as television but with the added allure of interactivity. My vision was clear: to merge the engagement of gaming with the visual appeal of TV, thereby revolutionising how we play.

But when it comes to claims like 'pets alleviate depression,' there's really no solid evidence. In fact, the findings so far are pretty ambiguous. And in one study that found no significant overall effect, cat owners were actually more depressed than the control group.

If you look at the balance sheets of Fortune 500 companies 50 years ago and today, you can see that 50 years ago, 80% of the value was physical stuff. Today, more than 85% of the value consists of intangibles. Companies must become so much more now that their value comes from their ability to inspire, drive and organise human beings.
