如果你不相信自己,就没有人会相信你。
If you don't believe in yourself, no one else will.
未来属于那些能够适应、创新并激励他人也这样做的人。
The characters I paint are not children, they have a rebellious spirit.
The only thing that can make you a better person is yourself.
Mathematics is not about numbers, equations, computations, or algorithms: it is about understanding.
数学不是关于数字、方程、计算或算法的:它是关于理解的。
——〈在广州岭南学堂的演说〉,1912年5月7日
育儿不是追求完美,而是建立联系。
