Do not see gambling as something that will save you rather see it as something who can destroy you, this way you will only play what you can afford to lose.
I disagree with this approach to gambling. Yes, gambling is not something that can save you(what is, btw?), but why precondition yourself that it can destroy you? People going to mountain climbing don't see it as something which can destroy them, although in some cases that is exactly what happens. Mountain climbers, or alpinists, see it as a great entertainment, which won't harm you unless you do something stupid. By "something stupid" I mean very risky moves, which surely give you more adrenaline than well-judged actions, but also can kill you most probably. Such moves can be compared to large bets with money one can't afford to lose in gambling. If you don't do such things your chances of being destroyed by gambling are small (although they do exist, so as for mounting climbers who can die sometimes even if they are very cautious). And this is not my theory, this is what statistics tell us: "approximately 1.6 billion people gamble during any given year with over 4.2 billion having gambled at one time or another". If even 10% of people who gamble were destroyed by it, that would be a horrible picture, but, fortunately, this is not what's happening in reality.
