There are a few factors that are important when it comes to quit our gambling career. First of all, how long have we been gambling? For people like me who are used to gambling for several years it's going to be much harder, than for someone who only gambled for a few months. Once gambling becomes part of your weeky habits it will be hard to change it again. Another factor is going to be how much spare time do we have. Let's say we become a millionaire and stop working completely, then we have so much free time every day and don't know what to do with it. It's going to be much hard to stay away from the casinos then. A good thing about life changing wealth coming from gambling is that we don't have any pressure anymore to win big in gambling. Once we are rich there is no need to bet big anymore. I think that my approach would be to still keep gambling and only bet very small amounts. Like that the risk of losing all my winnings again is fairly small and I still can enjoy the excitment of gambling.
While in theory a strategy like that would work, this is difficult to put into practice, and this is because of something called lifestyle inflation, so if at someone point on your life you were fine to make a one dollar bet and that was enough to bring you the thrill that you were looking for, once you become rich you will need to make a one hundred dollar bet in order to get the same kind of excitement, and as such you will have no other option but leave gambling behind completely as it no longer satisfies your entertainment needs, or you will increase your betting size until you can feel the same fun as before.
