Succeeding in business is all about making connections

I've taken many knocks over the years but it has only made me stronger and more determined to succeed.

Through the right people focusing on the right things, we can, in time, get on top of a lot if not most of the problems of this world. And that's what a number of us are trying to do.

I don't live my life thinking about "if only." I just try to think positively about the future. We'll never know for certain what would have happened if we'd gone to Iraq. The important thing is that we've got to do everything we can to prevent other wars.

All successful people - not just entrepreneurs - have got things wrong over and over again before finding the right solution.

Spend more time smiling than frowning and more time praising than criticizing.

With space travel, [it's] no different. You know, in 1990 I read the name Virgin Galactic Airways. Loved the name. And set out to try to find an engineer or rocket scientist in the world who could build a safe, reusable rocket that could take people to and from space and we could start a whole new era of commercial space travel.
