Staying the same means going backward, it's important for me to actually hear criticism sometime, because I think that's what makes me a better player and that means someone's questioning me who really cares about me, I think that's really important in the business world as well.
Roger Federer
不進則退,對我來說,重要的是要有時候聽到批評,因為我認為這是讓我成為更好的球員,這意味著有人在質疑我真正關心我的事情,我認為這在商業世界中也是非常重要的。
