Whenever I was planning a trip or a holiday, flights and hotels were easy. But when it comes to the stuff you want to do when you get there, working that out was really hard.

Wouldn't it be amazing if we spent as much energy investing in experiences as we do investing in things?

I kept being told, 'If you really want to build a start up, you have to be in San Francisco,' so I ended up taking out a suitcase. It did occur to me to do it in London but it's very, very difficult to build a start up in London - so I guess I was being lazy.

You can be this super-successful woman who's smart and effective but still feminine. When I worked in finance, I didn't always think that was possible.
