His father Alvin died of cancer when Day was 12. 12 歲時，Jason 的父親過世。
Before he passed away, his father gave him his first golf club – a rusty three-iron that he found in a junkyard. 他父親過世前，給 Jason 一生鏽的 3 號鐵桿！
Shortly after his death, Day began drinking - he was a confessed "alcoholic" as a school boy - and getting into fist-fights regularly. Jason 開始酗酒！
It was his mother, Dening, who - worried her son would be lost to the streets - sold the family's home when he was a teenager and borrowed money from relatives to send Day a few hours away to boarding school.
It was there he was given a book from his roommate about Tiger Woods and - amazed by the feats of the American at such a young age - Day began practising 30 hours a week to become what he is today. 讀了 Tiger Woods 成功的書後，他開始每週練習 30 個小時的高爾夫！
So no doubt there was a special thought for the woman whom he owes so much, watching back in Queensland.
Had he not become a professional golfer, Day figured he "would've been working at a meat processing plant, like he [Alvin] did".
