If anyone is advising you about how you cab turn your life around with gambling they are leasing you astray, gambling is a game of luck and you can never predict what will happen, it's over the human capability to know the future, this is why you need to be a responsible gambler.
People get lucky only when they don't see it coming, you should gamble in the same way, no expectations, just what you can afford to lose every time you gamble.
Stay safe.
