A big winning can fix your life as long as you did not continue to play and just stop it forever.
People usually being greedy , don't know when to stop and mostly ended up losing again, think about it.
That is a common practice of every gambler that he will never quit at the right time and will continue to gamble even if he have won good some of money and in the end loose every thing because most of the gamblers lack self control and that makes them loose in long run.
