Gambling increase your capacity of risk and this has positive effect on your life style for doing great work with little chance of success.
I think not only the positive effects alone. gambling also have negative effects, addiction to the game and time.
I think gambling is no positive effect, most gambling has a negative effect that would destroy your life.
the reply you gave is the history of the 80% gambler and the reason is greedyness and mostly everyone knows that casino gambling is long term loss, ya but sports betting in that you can win, not big but constantly in some ratios if you show greedy in this also then you cannot win any where
yeah you are right, any kind of gambling game if we are greedy and can not control the emotions, we will never get anything.
