I experienced what is called "beginners luck". I won some substantial money, but convinced myself I was an expert and could never lose...until I did.
Maybe this kind of illusion is what deceives many by the kind of first experience they are having towards gambling on tier first attempt on it, if we make win for the very first time and got impressed doesn't means that every other time we will be gambling will also have to be the same experience, we are to be more careful in times like this, because the moment we have the mind of making more win and it is not coming again as before then we are going to lose hope to start chasing after the mosses we've already made and this will only worsen the whole situation.
