I don't think about success to be famous, because I've done that at the highest level, but it's all about my children.

If I'm honest, I thought Westlife would keep going for longer than it did - we all did - but it sort of came to a natural end. When we decided we were going to split, I thought, 'If I'm going to sing, I'm going to have to do it solo.' Also, financially I was broke, so the decision was ultimately made for me.

I worry about putting food on the table, paying for my kids needs, their college fees in years to come. It's about earning enough to have a living to be able to look after your children.

When I had money, I felt pressure, whether it was to invest it or do good with it, and I couldn't let it fizzle out. It was like I needed to prove to myself that I could look after it, only I did the opposite, but you have to take a chance in life.

You know One Direction do a lot of up tempo songs, but when they did that Ed Sheeran song 'Little Things,' that was probably their biggest song off their last album, so it shows you that a ballad never goes out of fashion.

I put all my eggs in one basket and invested in property. I didn't do anything internationally - it was all in Ireland.

The adrenaline of performing on stage to a crowd - there's nothing like it.
