I know the question was not that simple but had nothing to do with being positive and negative.
Why are some people luckier than others? Surely being positive does not influence the numbers that come out in Keno. Or does it? Have some people worked out the secret to life? Because if life was that simple I would start being positive all the time and win all the time. Not that simple?
Here's an example.
Two guys walk into a bar. One is pretty glum overall, the other is smiling and happy inside.
If women had to choose which guy to talk to, and everything else was equal who would they talk to?
And gambling shouldn't come into it. Unless cheating, the odds for each game are (generally) the same regardless of the number of games played. Someone's perception of how lucky or unlucky someone is can be easily skewed by factors that you cannot see. (Eg. Bias in reporting - Only blagging about the wins, not the losses, betting large amounts per game/multiple bets on a game - so increasing their odds overall). A perfect example is if I bet on both Black and Red on Roulette, then I will just about always win. Am I successful or lucky? No.
