Prince William spoke about being a father and the "the idea of not being around to see your children grow up."
While chatting to British media personalities, Ant and Dec, the Duke of Cambridge revealed the ways fatherhood has changed him.
"I'm a lot more emotional than I used to be, weirdly," he confessed.
"I never used to get too wound up or worried about things. But now the smallest little things, you well up a little more, you get affected by the sort of things that happen around the world or whatever a lot more, I think, as a father.
"Just because you realise how precious life is and it puts it all in perspective. The idea of not being around to see your children grow up and stuff like that."
His words strike a chord with most followers of the monarchy, as the life of Prince William's own mother, Princess Diana, was taken when Wills was only 15 years old.
The interview was part of the documentary 40 Years Of The Prince's Trust - the Trust being a charity set up by William's father Prince Charles.
Will is married to the Duchess of Cambridge, Kate Middleton, who gave birth to the pair's first son, Prince George, in 2013. They later welcomed their first daughter, Princess Charlotte, in May last year.
