What tells me how to face our own shortcomings and mistakes is expressed in poetry?

It is human nature to make mistakes,

After that, it will be changed!

Change it if you have it, and encourage it if you don't!

Good and evil do not exist, and villains and gentlemen divide them.

Changing the map will not harm a gentleman, but will eventually become a villain.

Good medicine is good for illness, and Bai Gui's innocence is the only way to become a treasure.

If you want to build weapons, you must pursue them, and the mistake is not new.

Shao Yong's Ode to the Son

Fallacy became the reason for finding the result, and there was no trace of loopholes.

Experience should be summed up, and excuses should not win gold-(Tethysan)

Limestone hymn

A thousand hammers cut deep mountains,

When the fire started, it was idle.

I'm not afraid of fractures,

Leave your innocence in the world.

-Yu Qian (Ming)
