Zheng Qinwen's comment after 1st round win

Zheng Qinwen's comment after the 1st-round win in the US Open, ""This is the kind of match I would typically have lost in the past. Usually, after achieving some significant success, I would get too high on it, until reality hits me hard, bringing me back down to earth and reminding me to stay humble and keep working hard. This time, I kept reminding myself not to let it happen again; even after a success, I need to keep working hard and maintain a steady mindset.""
