It is all about the way how we take it forward. If we can keep ourselves under control, then it is possible to stay out of addiction. Lust is something that can be overcome concentrating on alternative things. Some might fail in it, but there is possible choices. If we consider gambling is similar to lust, then it is controllable. According to me lust on gambling and lust alone have got different meaning. Lust is some sort of feel, but with gambling there is money involved which could cause a negative effect than just lust which is much about feel.
You have raised a very good point and I want to address it. It should be called "lust and gambling".
Let's forget about the common meaning of "lust" (sex). Lust is when you desire something so deeply that nothing can stop you from achieving it. This is the right definition of lust. When you have lust for gambling then, based on the previous definition, nothing can stop you from playing/gambling. Keeping your self busy with something else or focusing on something else to forget about gambling may work if you are not lusting for gambling.
What is the difference between lust and emotion, so I think what is involved is not just a matter of mere lust. To be honest, I don't find the essence in the meaning of the word lust. The source that always triggers it is our own thoughts, and how dopamine plays an important role in making us enjoy gambling. and if we talk about lust, every human being has it and it is a natural trait that everyone has. and if lust is the trigger, then the initial trigger comes from emotion, and emotion is born from our own thinking. Whether what I say is true or false, this is just part of my point of view.
Well, whether it is easy or difficult to stop gambling depends on each individual. The thing is, everyone has their own way and how they react to it. In fact, there are many who find it difficult to stop gambling, because they are unable to fight their high desire to gamble. some others, it is easy to quit gambling activities. either by looking for other diversions, or indeed they only gamble at certain times. IMO, the point is, how do we define gambling itself. If we think that gambling is just for fun, do it without affecting the many aspects that have a detrimental impact on us.
