It only takes a player with absolute self-control to overcome all these attributes, because definitely there will always be a spirit of greed and love to play more but it is not meant to be harmful or destroy a player, it can be overcome by those who are determined to play rightly. And to correct your last sentence, nothing in life is worth getting addicted over.
Self-controlled is one of a good idea in contributing to stopping triggered you by the addiction. I strongly agreed with the reply above on me as what users stated. Don't prevail the greed over your self and most especially chasing a loss is one of the gambler's problems if they can't manage their selves and you've stated above was right "nothing in life is worth getting addicted over".
