Always go into meetings or negotiations with a positive attitude. Tell yourself you're going to make this the best deal for all parties.

Having the positive belief that it will all be O.K. just means that you hustle and make it work because failure is not even an option in your own mind.

I believe all positive things and negative things are valuable because they shape you.

Once you start a business, you have to grow it and grow with it - starting a business is not just for Christmas.

If you're a teenager in Palo Alto launching an app, you know from the outset how you plan to finance your business.

One of my goals is that, at a dinner party some time in the future, someone will say, 'Oh, my nephew is starting a ready-to-wear brand', and 20 people will turn around and say, 'Is he? Can we invest?' in the same way that, now, if you were to say, 'My nephew is starting a mobile app,' everyone would say, 'Oh, smashing! Can I invest?'

Work means independence. It allowed me to shape my life on so many levels.

My personal ambition remains the same - to be creative, to be modern, to stay one step ahead, to enjoy life.

My dad taught me never to be afraid of what's on the other side of the mountain.

I cry at anything remotely touching - smile at me warmly and I'm off... television also does it, everything from 'X-Factor' to cereal commercials. I cry when I am tired. I also cry when I laugh.
