Can you convince me that my statement is incorrect?
"I am always right."
Remember 'CAN' means 'WILL", if you can't, you won't.
If you claim you can do something and don't, during all time available. It means you never could, whether you were stopped by such things as fear, ability, desire, ignorance, lack of opportunity or barriers of any kind (whether labeled as physical or mental).
You can't even KNOW the statement to be false. To KNOW the statement to be false would require PROOF, and all you may have is EVIDENCE of any previous actions I may have made. (actions including statements I may have made.)
