In 30 years time, as technology moves forward even further, people are going to look back and wonder why offices ever existed.

Most of our businesses do succeed, but if something completely fails, then as long as we bow out gracefully and pay off all our debts, and nobody gets hurt, then I don't think people disrespect Virgin for trying. The public appreciates someone having a go; it appreciates the attempt. Who's been a success in life who hasn't failed?

I have always lived my life by thriving on opportunity and adventure. Some of the best ideas come out of the blue, and you have to keep an open mind to see their virtue.

I always tell other people to protect against the downside, and not risk roughing on new ventures, but I never stuck to that rule myself.

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.

Please don’t get hung up on this question of whether you need to have experience in an industry before you launch your startup.

Remember the to-do list but don't forget the to-be list.
