国家的繁荣建立在人民的勤劳之上。
The prosperity of a nation is built on the diligence of its people.
声音是一种天赋，但也是你每天必须努力练习的东西。
成功在于坚持和永不放弃。
《三民主义·民权主义·第一讲》（1924年3月9日）
Mathematics is the foundation upon which we build our understanding of the world, and it is through this understanding that we can solve the most complex problems.
主题并不重要；我想表现的是主题与我之间的东西。
The mind evolves to meet the demands of existence.
