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.

I have three children to take care; I have a wife. My job is to take care of them, and I can say it's a pretty cool job to have.

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.

You shouldn't end a band like Westlife and not be financially secure to some extent, but I wasn't at all - it was the complete opposite. But you look at stuff then, 'Well, what do I have? I don't have money but I have a great marriage, three healthy kids, and I have my voice. I'll just start again.'

I'd like to keep singing - whether that's small or big. To stop singing for a living would break my heart.

When you look at bands like Take That, who have come back bigger than ever, you can see there will always be a market for good pop bands.

Why me? Why did this happen? How could I be in Westlife and then have nothing to show for it financially at the end of it? But it's like, why not me? That's just life. It's tough. There's a lot more problems in the world. There are a lot of people who would wish to God they had my problem instead of having a sick child.
