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

I never went into business just to make money - but I found that if I have fun, the money will come. I often ask myself, is my work fun and does it make me happy? I believe that the answer to that is more important than fame or fortune. If it stops being fun, I ask why? If I can't fix it, I stop doing it.

All in all, the internet is a force for good, providing young entrepreneurs with access to an incredible wealth of information, has changed the way we see the world and is also a great source of innovation and entrepreneurial opportunities.

And obviously, from our own personal point of view, the principal challenge is a personal challenge.

I suspect in most companies, the public relations person is down at No. 20 in the pecking order. But here, he is fighting incredibly important battles. If a negative story starts running away with itself in the press and is not dealt with fast, it can badly damage the brand, and so we put enormous weight on our PR people.

I have always believed that business should be a force for good.

We're going where no one has gone before. There's no model to follow, nothing to copy. That is what makes this so exciting.
