Have passion for what you do; believe in yourself and your product and your customer; persevere; delegate; listen. Have fun. Today, I add: "Do good".

We'll go into orbit. We'll go to the Moon. This business has no limits.

No matter how big you are, details count!

We'll not be sending anyone into space before it is safe and the vehicle is well and truly tested.

If you want swashbuckling action in your life, become an entrepreneur and give it a go.

I was a risk-taker as a young man, and I don't regret it. I'm not adventurous in quite the same way now, but I still love the challenge of testing myself to the limits, flying around the world, or seeing if I can be the first to fly a balloon across the Atlantic, or trying to take people into space at an affordable price in an environmentally friendly way. I'll be going into space with three generations of my family!

I do believe the harder you work, the luckier you get.
