"Jonny Carmichael [Jubb's coach since childhood] has always ingrained that into my head because I did have a little stage when I was younger when I did get a little self-pity," Jubb says. "He always was like, 'This is your situation and you can't change it, so if you're going to moan about it, you're not going to get anywhere. You've got to make the most of what you've got.' From that point on that's always been the mentality I've had. It is what it is and you've just got to work hard."

Motivating Jubb, who studies retail management at college in the United States, during his rapid rise to prominence is the will to please those who have helped him through adversity. Whether that be Valerie for her care, Carmichael for his teaching on the court, his LTA mentor James Trotman for his advice or Josh Goffi for his coaching at the University of South Carolina, he is indebted to all for enabling him to become one of the most exciting teenage prospects in British tennis.

"A big thing for me is just making the people who have helped me along the way proud," Jubb says. "The ones closest to me know who they are. A lot of the reasons why I push myself so hard is obviously for myself and my self-drive, but a huge part of it is that I've had to have help along the way. A big reason why I try so hard and work so hard is for those people who have invested time into me."

Athletic since a young age, Jubb wanted to become a footballer, idolising Ronaldinho, the former Barcelona and Brazil midfielder, and replicating his tricks in the garden. A talented left-winger, he had the chance to take part in trials with Hull City, but he chose to focus on tennis. Inspiration to pursue a career with a racket in hand did not come from the usual suspects - such as Roger Federer or Andy Murray. Jubb followed the story of Frances Tiafoe, the American who was making waves on the junior circuit at the time after living in the office of a Maryland tennis centre with his father, who was an immigrant from Sierra Leone and worked there as a janitor. Tiafoe, 21, is now a top-40 player.

"I was watching a load of stuff about him on YouTube," Jubb says. "Obviously his background was pretty tough. He gave me a lot of belief to think that I can do it as well. From that point on I was fully invested in doing whatever I could to progress and hopefully make it on the pro tour one day. That was probably the big decisive point for me.  It would be nice to give people the belief that, if you do have a tough background, it shouldn't be an excuse. At the end of the day, it's down to you. If you're willing to put in the hard work, anything is possible."

Technically, as an amateur, Jubb can only claim from his £45,000 prize money what is necessary for travel and accommodation expenses. He intends to become a professional after completing his studies next year, but admits that transition could come sooner.  "If I won Wimbledon, maybe," Jubb jokes. "I am just figuring out what is best for me really. I am still young. I don't feel a rush right now to go on to the pro tour. I am still developing my body physically. I am happy to go back to college. Whatever is best for me I am going to choose."

*  Much of that is now fairly familiar territory, but there's still some new stuff, especially the bit about Frances Tiafoe's story being his inspiration.  There's an interesting interview with him in today's Times (behind a paywall).  Other papers are starting to pick up on Paul's story now, too.  There was even an article in the Evening Standard on Wednesday.
