YOU were not doing good. It was just that probability was in favor of you. You have no role to play in this other than clicking the 'BET' button. This is the dangerous thought that gets everyone ( including me ) into thinking that I have some role in influencing the outcome in the long run.
I know, but the day before i was doing so good, I had even thought of putting in some serious money.
Thank god i didn'tm it was only $5 investment, and in the end $20 lost
