I make a mistake from looking back at my experience because I see how terrible I am. I feel disappointed, and it makes me feel sick and discouraged from gambling. Yes, it is a mistake because the casino can't get more money from me after discovering my big losses, which makes me slow down and become an occasional gambler.
I believe a change could happen if we track our gambling history. But sad to say, that gambler never takes this seriously. Ignoring the past makes us still see a lot of gamblers in debt.
