Addiction means your mind want something in a regular basis to satisfy the dopamine needs.
Your brain has three status of living conscious,subconscious and unconscious.In the stage of conscious your mind knows what you are doing but on other stages you may not unaware of what is happening even if you are living in it.
So if you are having some habit to make you pleasure on short term like gambling,porn or dating and other lot of stuffs will become an addiction when you want that happiness everyday.But these things is not your long term pleasure it just only meant to be short term but your mind turning it into long term by making you keep doing it very often because your subconscious and unconscious make it as a habit already since you are doing it already.
If you want quit addiction from something then you may need to change your life style and concentrate on long term pleasure like building your career or doing workouts and getting success in your business like that.
Seems like a good advice for understanding the self which is for me, I find it really helpful. Too much of a something can do really make bad things to come that is why self-control and proper moderation when it comes to playing gambling as well as the other stuffs that you may think you find it as a source of your happiness. Do not be dependent on those things that are temporary in this world like playing and materialistic pleasure because you are not really just making yourself happy with those that you have, you are depending on those to make you happy that turns out to be your addiction through time. Seeking guidance from other people can somehow make up your mind but still you have to decide. That is why whenever I tend to play into an
online casino I am currently into, I always keep into mind that playing those variety of games are just for fun because social life and important matters in life like building my career is still the best happiness I could ever had.
