在数学中，提出问题的艺术必须比解决问题更有价值。
"When you do something best in life, you don’t really want to give that up – and for me it’s tennis."
Don’t worry how or where you begin. As long as you keep moving， your success will be far from where you start.
It is impossible to live without failing at something, unless you live so cautiously that you might as well not have lived at all.
当遇见生活中的困难，期许自己当那个为了未来起身奋斗的人，而不是直接屈服于失败。
Stay hungry, stay foolish.
