Afraid to get addicted - dont gamble. Pretty simple. Getting addicted to something is individual problem. There are people who gamble for many years and still not addicted. There are people who have lost their first bet, now chase that loss and all they think is how to stop this and end with profit. Imho it is impossible to tell when or after which bet a switch in brain will trigger and person get addicted. Important notice - repeatedly doing something does not mean addiction. Habit is not an addiction.
Well, I see your first sentence to be inaccurate, as it's not proper to cut the head simply because you are having a headache, gambling is not an automatic means to get addicted to it but how people take it causes the addiction. If you can't control yourself, especially your emotions and mind regarding gambling, then it becomes a problem. But this problem is not directly orchestrated by gambling but by the weak minds of the gamblers, so should we now entirely avoid gambling just because we are not man enough to be cautious and control ourselves, I say No. I for one is not addicted to gambling and what has helped me most is the fact that I do not take anything too seriously, esevailly when it involves money. This is in addition to the fact that I have a very strong mind, I mean I have my on mind that I can control actively, and this has helped me to have my say over gambling.
As for beginners or anyone who is fighting gambling addiction, they should go back to their drawing table of initial learning and mind shaping towards it, if not, it will never stop and it could get aggravated into more issues. If gamblers are pre-warned about the issue of gambling and prepared to be cautious towards it, it will never be an issue for them. They will gamble with care and calculatively, to the point that they will never put their minds on the money to be made through gambling but will always resort to the true fact that gambling is more luck-inclined and nothing more.
With this understanding, and with the right preparation and expertise in the areas of planning, budgeting and management, and also in the preservation of a balanced psychology, I am sure that the gambler will be a better person void of addiction and other gambling issues.
