Sports stars have often had to make do with less than glamorous settings as they worked and toiled their way to the top.
Today's players are often derided for being spoilt rotten by pristine pitches and perfect facilities at modern academies, but it has not always been this way.
Pele - arguably the greatest footballer to have ever played the game - famously grew up honing his skills with a grapefruit because he did not have enough money for a ball.
Sir Donald Bradman used to hit a cricket ball with a stump, not a bat, to work on his skills; while Novak Djokovic developed his tennis talent by hitting a ball against the sides of an old neglected swimming pool.
Equally, legendary boxer Joe Frazier, while working at a slaughterhouse, developed a habit that would later be immortalised by actor Sylvester Stallone in the boxing movie Rocky as he practised his punches on the hanging sides of beef when he moved them into the refrigerator.
There are countless examples of top stars working their way to the top despite limited resources and facilities, but David Beckham is not someone that would be expected to fit into this category.
Indeed, money may not have been the issue but, as he has revealed in an extract given to The Times newspaper from his new book 'David Beckham', he had to work on his skills in less than conventional fashion.
Beckham was renowned for his ability with free-kicks during his illustrious playing career, but he has now explained how he came to specialise in such situations.
"When my dad got home from work, we would go over to the goalposts together," he said. "He would stand between me and the goal, forcing me to bend the ball around him. People looking on must have thought we were mad.
"We kept going even when the sun had gone down, playing by the light coming out of the windows of the houses that surrounded the park.
"I would carry on playing when I got home. I wasn't allowed a football in the house so I would practice by kicking the Care Bears in my sister's bedroom," he added.
"My mum thought it was funny but it showed how much I loved football. I couldn't get enough of it.
"I must have taken tens of thousands, maybe hundreds of thousands [of free kicks]. I would go to the local park, place the ball on the ground and aim at the wire meshing over the window of a small community hut."
So Beckham's sister may have been upset by her Care Bears having the actual stuffing kicked out of them, but it all helped the former England captain become the player that he did.
And with Becks' current personal fortune, we are certain he reimbursed his poor sibling for the damages...
There is often quite literally nothing that will prevent a top sportsman or woman reaching the top, as the many examples already cited prove.
