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.

The proactive approach to a mistake is to acknowledge it instantly, correct and learn from it.

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.

It's easy to say ''no!'' when there's a deeper ''yes!'' burning inside.

People and organizations don't grow much without delegation and completed staff work because they are confined to the capacities of the boss and reflect both personal strengths and weaknesses.

The test is to recognize the mistake, admit it and correct it. To have tried to do something and failed is vastly better than to have tried to do nothing and succeeded.
