Argue for your limitations and they will be yours

I noticed something interesting while analyzing charts in the stock market today. When an investor owns a stock that is dropping in value they will often look for indicators that show the stock will reverse and rally back up in price. This investor is intentionally looking for validation for their situation rather than accepting what it is, a loosing investment, which prevents them from taking action. I see people do this same thing in many other aspects of their life. It reminds me of a quote "argue for your limitations and they are yours."
