Mine is I always check my wallet balance to check my current profit then place a small bet without any reason just to gamble and increase my profit. This makes me gamble frequently because of the greediness to earn more until I become hooked and worst is when I lose everything on a bad day.
You are definitely not the only one in this and this is the way gambling addiction start for every gambler who have not been able to get of their addiction, losing and chasing it back is the debacle as a gambler addict.
Of course if a gambler can see what will befall him in his next game, the falls and failure that will automatically change his course of gambling, he would not want to continue the next game and this is because it starts from there. When you lose, you become restive and sometimes annoyed on your losing probably because you think it was a narrow lose then you want to try next game believing you will succeed. So addiction always starts from pushing too hard to win back.
