As far as one can afford loss and doesn't hamper his life financially, he can go and gamble for fun. But keep gambling everyday just not to miss a luck day is stupid act. What if he finally wins in 31st dec losing all year from 1st of jan to 30th of dec? Is that win even worthy? Can he wins back what he lost at least in just one win losing all year? Winning amount most probably will be just a small fraction of what he would have lost. So one should gamble with responsibly and for fun with the amount he could afford even with loss.
