I feel no one can tell you that. sometimes people look at your victory and tell you that today is your lucky day, but I guess it was just luck passing. I could taste it is yourself. but sometimes, you feel that it is your luck and try it again, and you finally hooked. Well, feel lucky you have.
Correct no one tell when your luck come. You have tried with your own money to get your lucky day. It will not come daily in gambling you have to wait for a long time. But when your lucky day comes you will make huge money in gambling. When you win your bet, you feel that is your lucky day that's it.
But it is only when we win a big bet and if we never lose again than definitely, we can say that it is our lucky day, but many time we win but we forget to remind our self that is our lucky day. Because luck and greedy both have comparative with each other, our luck give us win but our greediness always give us loss.
But as he asked us in thread, I want to say, Luck is not a thing when it will come than we see, it is a feeling, we can only feel it and guess about it.
