When gambling you don't have to expect but can only hope you get lucky though you still don't have to rely on the hopes because you could feel disappointed losing all with no single win to boast of for the day.
It's normal for all of us gamblers to expect and hope that there is something good that is about to happen with those bets that we do. In casino games, in sports betting, all hopes are the same and we just want to have one thing and that's luck for us to win all of those bets. But you're right, do not expect a lot so that you won't be disappointed when losing has come.
When we put expectations forward we get tempted to push over our limits and stake with such amounts that will hit badly if we lose it. I idea that you would win huge by staking so much high could definitely lead to a torn pocket.
The bigger the risk, the bigger rewards are potential going to come and this is a real gamble and think of it if you can afford to do that. Because not all of us are this kind of gambler that is willing to do everything and what it takes to gamble.
