You couldn't possibly be worse than Issac Asimov:
My brother, Stanley, who watched us play, learned the moves and, eventually, asked if he might play. Ever the indulgent older brother, I said, "Sure," and prepared to beat the pants off him. The trouble was that in the first game he ever played he beat me.
In the years that followed, I discovered that everyone beat me, regardless of race, color, or religion. I was simply the most appallingly bad chess player who ever lived, and, as time went on, I just stopped playing chess.
Never quit! Take a few weeks off, and then come back and try again!
