Gambling can change the course of your life at any moment. It is the shortest path to success in life. However, the amount of success and failure is equal. No one can say you will succeed or fail.
Do not be tempted to see someone can be successful or can achieve a win with a huge amount that will change his life because it is very possible that he has been through it long enough to be able to achieve that and also the money he uses is also big, no one knows only he knows.
I would not personally dare to glamble in order to try to change the course of my life, because obviously that would require anyone to invest a significant part of their savings and because of the luck factor. In my opinion it would be ideal to gamble keeping the expectations low and with only only one is willing to lose to a bad luck streak. I am aware that there are some professional gamblers that manage to accumulate a good quantity of money, they take it as a job/career and are commited to it and have studied their strategies to increase their chances of profit. One should not confuse casual gambling with career gambling.
Gambling could change your life if you are extremely lucky and one single bet could land you into that comfort zone of life but it should not be expected from gambling at all because this is the way to be financial breakdown.You want to have fortune with it and will bet high in hope to win the same seeing someone else but it won't work and you will loose you savings also.So for me it's fun part and if you are lucky you can win something from it.
