历史学家必须怀有一种信念：人类不会也不能灭亡。
The historian must have a kind of faith that humanity will not and cannot perish.
生存，还是毁灭，这正是问题所在。
You can't go back and change the beginning, but you can start where you are and change the ending.
Will inertia be your guide， or will you follow your passions？
The best armor of old age is a well-spent life perfecting it.
引用李育辉
Adaptability is the cornerstone of resilience in an ever-changing market.
