There is an interesting article on him from 4 years ago
here
My favourite quotes:
Richard [Branson] asked me along on his inaugural flight from Heathrow to Mumbai, and I flew my girlfriend in from Chicago to come along. Then she dumped me on the first night for a journalist.
"Until yesterday I thought I was normal. Then last night I thought: 'No girlfriend, haven't seen my friends in ages,' so for the first time it hit me that it has affected my social life quite a bit. Most of my friends are older. But it's all part of it, I suppose, and I am so excited about this airline that I can put that off for a bit."
I'm baby Branson and this is mini Virgin. We're not that different. We both started young.
