While 'Teachers' may have had its following, it was on late-night Channel Four, whereas 'EastEnders' was seen by millions and millions of people. I certainly don't have the cache to sell a programme like that, and certainly nobody's coming up and asking me to.

I loved doing 'Teachers.' I don't know if it's set me on a road, but it certainly got me out of financial penury for two years. But as much as I love it - and it's a huge sacrifice - as much as I love it, I'm in acting because I'm searching to do lots of different things.

My fantasy life was very full. Certainly when I was a kid, I probably wanted to be an actor because I wanted to be a princess, or something magical, and get to dress up magically, and have the kind of life that I hadn't been born into, with magic powers or whatever, and live this wonderful idealised life.

If life is going well, I watch quality things like period dramas and 'The Blue Planet.' But other times, I'll trawl through anything Freeview has to offer. I do believe TV can ruin your mind, but it can also be a really good friend.

It was only when I started handling Treasury Operations that I realised all of a sudden just how much wealth we have. That is a huge responsibility, so I decided to get on with it and learn how to manage it, because I am a single child and have no siblings to share the responsibility with.

So much business is based on the belief that we should do whatever we can within legal limits to make as much money as we can. Ben & Jerry's was based on values, and we try to operate a business that not just sells ice cream but partners with all our stakeholders - whether that's suppliers or customers - to bring about a more sustainable world.

We think that in Mexico, online trading of shares and financial instruments is not going to be as important as it is in the U.S. On days that there is a banking holiday in the U.S., you hardly see any movement here on the stock exchange.

Roku collects money two ways: by selling hardware, which it calls 'players'; and by selling advertising and taking a cut of revenues from the video publishers on its platform.
