Prince William may have a royal title, but when it comes to parenthood, he admits he's just like any other dad.

During his two-day trip to Vietnam this week, The Duke of Cambridge stopped by Talk Vietnam, an English-language Vietnamese talk show, where he got candid on what it's like raising his two children, Prince George, 3, and Princess Charlotte, 1, with wife Kate Middleton.

"There's wonderful highs and wonderful lows," he said of fatherhood. "It's been quite a change for me personally. I'm very lucky in the support I have from Catherine, she's an amazing mother and a fantastic wife."

"But I've struggled at times," he confessed. "The alteration from being a single, independent man to going into marriage and then having children is life-changing. I adore my children very much, and I've learned a lot about myself and about family just from having my own children. It's amazing how much you pick up just in those moments."

Prince William, who is the older brother of Prince Harry, admitted he's still getting used to "having a girl in the family," as he never had a sister growing up.

"Having a daughter is a very different dynamic," he said. "So I'm [still] learning."

As for Prince George? "[He's] a right little rascal sometimes," the Duke joked. "He keeps me on my toes, but he's a sweet boy."

Now that Prince William is raising a family of his own, a role he says is "wonderful," "fantastic" and "very important," he has a much different outlook on life.

"I worry about the future more," he revealed. "When you have something or someone in your life to give the future to, I think it focuses the mind more about what you're giving them. I would like [my kids] to grow up with more simple aspirations. I think there's a lot of huge aspirations and people living with an enormous amount of stuff that they don't necessarily need."

"The materialism of the world -- I find quite tricky sometimes," he continued. "I would like George and Charlotte to grow up being a little bit more simple in their approach and their outlook, and just looking after those around them and treating others as they would like to be treated themselves."
