Gamblers needs to realize that they must have limitation in gambling so they will not spend too much money especially if they want to test all of their strategies in betting. They must know how to allocate the money for each of their strategy so that will not makes them spends much money. But they must understand that when the strategy success and give them a good outcome, that strategy may not works anymore in the next match. They need to prepare and use the other strategies that can works so that will makes them spends more money. But if they realize about this, they will not push them hard to test all of the strategies because they know that will require a lot of money before they can have the right strategies.
People who are addicted will not easily be able to realize that they have limits in gambling, one way for them to find their point of awareness in my opinion is that they must be helped by being reminded that they have gone too far in gambling, although there is a possibility that this will not work but at least we have made an effort. The same thing happened to my brother who was addicted, I did this option but it didn't work and until now he still likes to gamble.
Many people have confidence in their own strategy which they believe can make them win and maybe it can work, only I think it will only work once in a while, when they have managed to win and then return to using the same strategy I think it will not be able to make them continue to win because basically there is no victory that can be obtained consistently even though using the strategy at once.
