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

I myself have benefited from many mentors throughout my life.

We [Virgin Group] have been successful not by wasting time scrutinising our competitors but by looking at ourselves from the point of view of our customers do and seeking feedback through listening.

So unlike having to convert, you know, all the cars' or all the lorries' petrol stations, once you've actually got the clean fuels, it's relatively easy to, you know, get it to the airplanes.

It's really important to find an hour or two to a day to make sure that you keep healthy, keep fit. It's very easy just to forget that aspect. And if you're feeling really good and fit, I think you can get two or three extra hours a day of hard work in as well.

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

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