David Beckham tells his children: 'You'll never get anywhere without making sacrifices'

With an estimated fortune of £ 700 million, David andVictoria Beckhamwould probably say they achieved that success through hard work and perseverance.

And they want their four children to do the same – even if it means missing out on fun with their friends.

Beckham, 44, revealed yesterday that he encourages his children to forego nights out with their mates so they can develop their careers.

Asked what advice he gives Brooklyn, 20, Romeo, 17, Cruz, 14, and eight-year-old Harper, the former England captain told GQ magazine: ‘To work hard, simple as that.’

Brooklyn is a model and photographer, and Cruz is said to want to be a pop star like his mum, former Spice Girl Victoria.

Beckham added: ‘I tell the kids they have to make choices, sometimes give things up. If your friends are going out on a Friday night, maybe you can’t. Maybe you’ve got tennis practice the next day or you’re in the studio singing, like Cruz, or you’ve got a shoot, like Brooklyn. That’s where your focus needs to be. ‘

The former Manchester United star is to be honored at tonight’s GQ Men of the Year awards, and appears on the cover of the magazine’s October issue.
