By the time Ellie-Rose Griffiths was nine, she had left school to train full-time. That was when tennis stopped being just a game and became her life.
The former top-ranked junior player would go on to compete alongside some of the top names in British tennis including Katie Boulter, Emma Raducanu and Harriet Dart before stopping playing at 19 because she was burned out and not enjoying it any more.
When the 27-year-old looks back now, it is not just the tennis she remembers. It is the pressure around it, and in particular one group of people she believes could deal with it better.
Parents.
Pushy parents are nothing new in a sport offering the potential of millions of pounds in prize money at the very top - at elite level there are well-documented incidents involving the dads of Jelena Dokic, Mary Pierce and Bernard Tomic to name a few.
It all starts at junior level.
"You see parents shouting at children all the time in tennis," Griffiths tells BBC Sport. "There's a lack of understanding on how they should behave... on how they could help their child to blossom into the athlete that they should become."
And it can get out of hand.
"We've had situations here before where unfortunately we've had to call the police because the parents' behaviour is getting that far out of control," says Chris Johnson, head coach at Sutton Coldfield Tennis Club, where he has worked for 36 years.
"They won't listen, they think they can get away with anything, they don't respect the referees, it can get a bit ugly."
Both are clear that behaviour like that does not happen in isolation and that it is the environment tennis creates that makes parents behave this way.
So, why is that and what needs to change?
Tennis can be intense for parents.
There is transport to arrange, coaching to fund, and a complicated player pathway to navigate. In some cases there's even private tutoring to arrange if their child has left mainstream school to focus on the sport.
"You do get on a bit of a hamster wheel", says John from Derbyshire, whose 11-year-old son Harrison is a promising player. "It's 12 months of the year, indoor courts and outdoor courts."
Children can start a form of tennis from the age of four on a modified court. The Lawn Tennis Association's (LTA) performance pathway for the most promising juniors supports players from the age of seven on their journey to potentially becoming a Grand Slam champion.
Competitions are grouped according to age and start aged eight and under.
And the ratings and rankings you get from doing them are one way to get noticed.
So when does it start to get serious?
"The minute they start playing their first competition," according to Johnson.
Does he think that is right?
"Absolutely not.
"A lot of adults can't cope with the pressures of playing an individual sport and then they're expecting young children to be able to do so."
Steve Whelan, a coach working in St Albans with nearly three decades of experience, agrees that the system places too much emphasis on winning at a young age.
"It just creates this race to the bottom because parents are chasing ratings and rankings," he says.
He tells parents: "These are not tennis players. They are kids who play tennis and there's a big difference."
The LTA says it undertook a "comprehensive review" of its rating and ranking system in 2018 "specifically to address the issue of putting too much pressure on children at too young an age."
Now players can't be ranked nationally against their peers until they reach the under-11 age group, with younger children from eight and up organised into competition based on recent form - a rating.
When it comes to parental behaviour the LTA says like any sport "there are occasions when a small minority of parents do not uphold the standards of behaviour expected". The governing body will soon be launching a new initiative called Fair Play, to promote positive parent behaviour and support coaches.
