The process of reviewing what you write, or think, and comparing it to what actually happened, can be incredibly valuable. You learn most from your own mistakes.
To those, however, who are so biased they refuse to accept even the things that they have written, that are clearly wrong, misguided, and biased ere doomed to suffer the same fate again.
When they blame and insult others they lack character.
If you like losing money, and refused\ to Acknowledge what you have written, make jokes, and try to blame others by insulting them, and fail to accept your own mistakes, and can't even support words that you have written, you are lost not just financially, but to your core.
As TS Elliott wrote: "The bad poet is usually unconscious where he ought to be conscious, and conscious where he ought to be unconscious"
I suppose those who look to deceive others, May find it hard to know where the lies and the truth are, and ultimately deceive themselves as well.
