It felt when I was growing up that sport was, like, the only thing you should do... if you do music, you're really different and a bit weird.

I'm involved in music and fashion a lot more than I used to be, so my style has definitely changed - for the better, of course. It's given me greater insight into what colours work, what looks good on camera, and what I feel comfortable in.

I've only really had one period when I lost myself and felt like I was going to lose my career, and that was when I first began presenting 'X-Factor' spin-off 'The Xtra Factor' two years ago. I was worried if I did a rubbish job live on Saturday night TV that my music career was going to get affected and I would lose everything.

I'm a huge fan of 'Heart On My Sleeve' - I think it has a 'Take That' feel to it! John Shanks and James Morrison wrote the track, and we spoke to Sony and asked if we could reference a 'Greatest Day'/'Rule The World' sound to make that epic ballad. I think it does the job.

No matter what, the way to learn to program is to write code and rewrite it and see it used and rewrite again. Reading other people's code is invaluable as well.

My father always encouraged me to get an education, but he was also a guy that, when he was younger, had ridden the rails from town to town to box and wrestle for money.

Being able to save, make non-cash payments, send or receive remittances, get credit, or get insurance can be instrumental in raising living standards and helping businesses prosper. It helps people to invest more in education or health care.

My dad encouraged us to fail. Growing up, he would ask us what we failed at that week. If we didn't have something, he would be disappointed. It changed my mindset at an early age that failure is not the outcome, failure is not trying. Don't be afraid to fail.
