We have the enormous opportunity in our hands to make a positive difference for business, people, and the planet.

Publicity is absolutely critical. A good PR story is infinitely more effective than a front page ad.

Your brand or your name is simply your reputation, you have to fight in life to protect that as it means everything. Nothing is more important.

Well, I think that there's a very thin dividing line between success and failure. And I think if you start a business without financial backing, you're likely to go the wrong side of that dividing line.

I've been in Africa, and I've been to hospitals of Africa, and they're not hospitals, they're places where people go to die. And rows and rows and rows of people just dying and the waiting rooms of the hospitals are full of people waiting to get into the beds of the people who died the night before, and they're dying from unnecessary diseases.

There are no quick wins in business - it takes years to become an overnight success.

I think a lot of becoming an entrepreneur is something which people have to learn just from getting out there and giving it a go, and having to learn the art of survival.
