[on his friend, the innovative rock star Peter Gabriel] In the early days, we'd go skiing together and Peter would have an idea every 30 seconds. We'd be sitting on the lift with me scribbling madly in my notebook, trying to get everything down. He's worse than me.

[the test-flight crash of a space-flight craft, October 2014] There is no way I would ask others to go on a Virgin Galactic flight if Indidnt feel it was safe enough for myself.

For a while now, space has been looking boring. News about space was reduced to budget cuts and deorbiting schedules, not research and innovation. Then, the private sector began designing spaceships to send payloads and people into orbit and beyond. Today, teams like Elon Musk's "SpaceX" are reopening space for exploration..It's a paradox that Elon is working to improve our planet at the same time he's building spaceships to help us leave it. But true vision is binocular, and Elon Musk is clearly a man who can see many things at once.

Don't forget: never accept the unacceptable. Now we just need to get on with it and make it happen - quickly. Can you imagine what a different world we will live in when businesses do what's right for the communities and the environment in everything they do?

The majestic and powerful polar bear is an iconic symbol of Canada around the world. With their habitat increasingly threatened and their very survival in jeopardy, now is the time for action. We owe it to the next generation to ensure that these magnificent animals will live on.

We're one of the only animals in the world that don't really think of ourselves as animals, but we are animals and we must respect our fellow animals.

I'm a lad of the '60s. I started a magazine to try and end the Vietnam war, but it was a number of years before I had the profile, the financial resources and the time to do more.

To me, business isn't about wearing suits or pleasing stockholders. It's about being true to yourself, your ideas and focusing on the essentials.

If you're embarking around the world in a hot-air balloon, don't forget the toilet paper.

I'm a bit like the Queen in that I don't carry much cash.

The funny thing is people won't let me pay for things. I'll be in a restaurant and the manager will say: 'Oh no, it's on the house.'

A generation ago, the image was that you had to trample everyone else down to succeed - but I don't believe that makes good business sense. If you're the kind of person that jumps down the throat of people, you're not going to be successful.

For a successful entrepreneur it can mean extreme wealth. But with extreme wealth comes extreme responsibility. And the responsibility for me is to invest in creating new businesses, create jobs, employ people, and to put money aside to tackle issues where we can make a difference.
