It is just our of the frustration of the certain gambler to say that gambling is wrong but when they feel to gamble anymore they still patronize gambling, the decision to gamble is by our selves so we need to be responsible enough to play on our game and accept whatever the outcome may it be bad or good for us.
There is no such thing that gamblers didn't learn anything after loosing in gambling, sometimes we need to realize that after gambling, we do have a learning's that remained to us. although it is small or big, it is still have, And we also have to realized something after that, I don't know what is it but it is also depends.
