"I used to repair those balls that were bad and torn in the squash court that guys used to throw away with tape and glue."
Taliban's unwanted attention
A steady improvement in her game led to appearances in high profile tournaments and prominence in the Pakistani media.
Awards from then president Pervez Musharraf and prime minister Shaukat Aziz were a mark of her pioneering spirit, but they also attracted the Taliban's unwanted attention.
"It was exhausting at every step," she said. "It was hard to let people know all I want is to play squash. That's how I can live happy but I had to change my life with time.
"For the last eight years I've been trying hard to come through to the common people and today I'm getting threats from Taliban. I was totally exhausted. I didn't know what to do.
"I stopped going to the academy because it's the biggest dishonor if a daughter is kidnapped. That's (why) I locked myself in my room and started hitting from evening to morning."
Her absence was noted and when she relayed the threats she'd received the issue was debated in parliament, who reacted by beefing up security around her.
"They put so many attack posts on the way to the squash court and around the squash court too," she said. "Above the squash court they put snipers.
"I was going once a week or twice a month but at that time I completely stopped because if a bomb happened -- there is so much glass in the squash court itself -- it would kill the innocent kids.
"I didn't want it to be the reason so I stopped going and started playing in my room for three-and-a-half years."
It was during this time Wazir says she knew she had to leave Pakistan to follow her dream.
"My dad said 'If a baby bird wants to learn flying, he has to leave the nest' and at that time I realized I cannot learn flying while am here.
"For three-and-a-half years I didn't get any email from anyone and one day I got an email back from Jonathan Power saying that he's going to help me, support me, teach me how to play squash so I can play at tournaments and become a world champion for Pakistan."
Power himself was sent to London as a 12-year-old to train with former Pakistani world champion and all-time squash great Jahangir Khan, and was immersed in the culture of Khan's country, traveling to play there on many occasions during his career.
Wazir's plea struck a chord with Power, who flew her to Toronto and has since been working on building her strength and stamina, and molding the rawness of her technique into a formidable weapon.
"I recognized right away this girl is special, she's very courageous girl and I wanted to help," said Power.
"She'll run through that wall 10 times until she finally breaks it. She thinks working hard just means killing your body and you'll get better, but sometimes you have to work smart.
"It's so rare to find somebody who has so much drive and so much passion, who is just dying to absorb knowledge. I think she's going to make it to number one in the world.
"She knows it's going to take a lot and she's prepared to sacrifice whatever it takes. I think she has the skills and the mental ability to make it all the way."
As for Wazir, her ambition to be the finest player on the world is now allied to a desire to campaign for other young girls in Pakistan to have the freedom to explore sport.
"I feel the luckiest person and I think whether my hard work turned me into being lucky or if I am the chosen one to bring change to the world," she said.
"I learned it's more about humanity. It's not about religion, it's not about culture or caste or tribe or where you're from or the value of the background of the person.
"It's all about being a human. I learned a lot and squash taught me. Through squash I made it and learned otherwise I'd be stuck in those tribal regions.
