I don't know about any other person but personally, I've come to discover that winnings that are unexpected excites the most than the winnings that are expected, regardless of the amount of money involved.
Normally, winning a game unexpectedly is more sweet and encouraging than winning an expected game. If you are expecting to win a game, you will definitely have a plan for that win, but if you just take the risk of playing without expecting any win and you end up winning, you will be the happiest person on this earth.
Although my experience on this was not a good one because most of the time if I am expecting to win a game, I mostly end up losing it, but any game that I don't expect to win, that is the game that I mostly win, so even if I am to gamble, I always keep in mind that I might win or lose, and I don't make it to myself like a most for me to win. That is how I actually play my game. I always expect the unexpected.
