I am not saying anything against this argument but there are times when the gambler wins and also win good and they are too much happy about the progress. A very few people discuss about this and only talk about the negativity they found in gambling.
What tends to catch people's fancy the most is how much loss you've generated over a specific period of time -- especially wagering a $100k at once on a single ticket.. Nobody says you should fold cause you lost today, you can possibly win some other time.
The last thing I'd do is use the reverse phycology method on a game of luck and chance.
