If one has made a mistake, and fails to correct it, one has made a greater mistake.

One mistake I make is to care too Deeply, that is one mistake I don't care to correct.

An error doesn't become a mistake until you refuse to correct it.

One fails forward toward success.

A great nation is like a great man:
When he makes a mistake, he realizes it.
Having realized it, he admits it.
Having admitted it, he corrects it.
He considers those who point out his faults
as his most benevolent teachers.
He thinks of his enemy
as the shadow that he himself casts.

Don't argue for other people's weaknesses. Don't argue for your own. When you make a mistake, admit it, correct it, and learn from it / immediately.
