我从十五岁开始致力于学习，三十岁便能自立于社会了，四十岁对各种事理不再迷惑不解，五十岁懂得了自然界的规律，六十岁对听到的事情能领会贯通，并能辨别是非真伪，七十岁时做事能随心所欲，但又不会超出礼法的规范。
预测未来的最好方式就是创造未来。
"To live is the rarest thing in the world. Most people exist, that is all."
Make up your mind to act decidedly and take the consequences. No good is ever done in this world by hesitation.
