Big wins will definitely come and every gambler has this opportunity, it's just that when the time comes, no one knows, so it's better to gamble for fun so that the wins can come by themselves.
Yes you are mate, we must gamble for fun only and not have the mindset that we can earn daily a big amount of money because in the world of gambling we can not predict the outcome of our every bet. Sometimes we will win and sometimes we will loss. So it's better to aim happiness than profit. Here in in my country some gambler loss big amount of money because they are aiming profit. Once they put a bet they will mind that they will win and if they loss then they will double or triple their bet.
