There are no coincidences when it comes to elite sport. Whilst there is no allowing for pure talent, in all other respects, preparation is everything. Results reflect input - period.
Novak Djokovic’s win at Wimbledon is not something that just fell into his lap. It was the product of the most meticulous and sustained attention. His competitive excellence is the product of exemplary preparation. There may be millions who like to bet on their exploits, but Wimbledon champions these days leave no part of their off-the-court regimes to chance. You get what you train for, and that is just as true of diet as it is forehands and backhands.
No-one gets handed success on a plate, but what you serve up at mealtimes is a key ingredient to getting the most from your talent.
