Teenage Dream' was the hardest breakup for me.

One thing I'd tell an up-and-coming singer is to never rely on other people for anything. The more self-sufficient you can be, the better off you'll be.

There's a lot of little 'Bonnie-isms' in 'Teenage Dream' that I was hoping to keep for myself.

In my mind, I imagined L.A. to be skyscrapers on the beach. Of course, that's not what it actually looks like. And growing up watching 'Beverly Hills 90210' and 'Melrose Place,' I always had an obsession with L.A. and California in general.

Technology can be a great equalizer when it comes to health care, education - to the point where rich, poor, middle class can all get the same benefits.

Online business models are still evolving. New and different products and services pop up every day. This gives rise to supporting products and services. A business can make substantial profit by helping others execute their plans for making money.

My life has changed, but I'm not money-motivated at all; that's the last thing on my mind. I just want to play football, and that's how I've always been.

It's mostly the financial chicanery that's going on. People are saying 'What kind of trust can we put in this market?'
