Most of the addictions avoidance techniques are effective for those who haven't had hard cases of addiction in the past, e.g a newbie who is just coming into gambling can choose to make use of that system to stay away from addiction, which is the best thing to do at some point because for all the while, I have not seen any workable approach that can bring one out of addiction and helping him stay above such, and that is why, it is better to avoid gambling addictions because it can ruin your life at some point.
Most cases of gambling addictions are traceable to over-involvement and chasing a direction for so long, meanwhile, the best way to stay above that is never to state and always allocate limits to all your gambling activities regardless of what the result and outcome may be at the end.
Regardless and you need to firm in terms of limiting yourself, both finances and time that you will going to use each time you play or each time you deal with your participation into gambling, if you can take that and not to allow yourself to exceed the chance is good that you will be able to avoid going deeper and lead your way to become addicted.
With control and limitation that you setup, there's no chance for any excessive participation which will allow you to quickly quit and stop each time you desire to quit.
