朱熹·《答黄嵩老》
大抵人情若干由于，多致因循，一向懒废。今但心所欲为，向前便做，不要迟疑等待。即此目下顷刻之间，亦须渐见功效矣。
年运易往，时不待人，况中年以后，尤宜汲汲也！
《朱文公文集》
A Reply to Old Huang Song 1
Zhu Xi
People are generally apt to hesitate time and again before doing things, which often leads to delay or failure. If you want to do anything, just go ahead without any hesitation. Your efforts can begin to have effect even in a moment of time.
Time is fleeting and will not wait for us. Especially we middle-aged people should seize the day and race against time.
Collected Works of Zhu Wengong
1. Huang Song was a friend of Zhu Xi’s.
