I was a risk-taker as a young man, and I don't regret it. I'm not adventurous in quite the same way now, but I still love the challenge of testing myself to the limits, flying around the world, or seeing if I can be the first to fly a balloon across the Atlantic, or trying to take people into space at an affordable price in an environmentally friendly way. I'll be going into space with three generations of my family!

One night, I was chatting with a group of 16-year-old girls over a few drinks about a name for the record store ... A bunch of ideas were bounced around, then, as we were all new to business, someone suggested Virgin. It smacked of new and fresh and at the time the word was still slightly risqué, so, thinking it would be an attention-grabber, we went with it.

The ability to bounce back after a setback is the single most important trait an entrepreneurial venture can possess.

To achieve consistently terrific customer service, you must hire wonderful people who believe in your company's goals, habitually do better than the norm and who will love their jobs; make sure that their ideas and opinions are heard and respected; then give them the freedom to help and solve problems for your customers. Rather than providing rules or scripts, you should ask them to treat the customer as they themselves would like to be treated - which is surely the highest standard.

Train people well enough so they can leave, treat them well enough so they don't want to.

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

The first thing to look for when searching for a great employee is somebody with a personality that fits with your company culture. Most skills can be learned, but it is difficult to train people on their personality.
