If we are talking about gambling, expenses must exceed income most of the time, and things will still be very normal, but then, there is actually a level that a gamblers loses can get to, it becomes a red flag, which is why it's important for gambler to always recognize the size of their pocket as well as their bankroll, and always set a stop loss for themself, just incase of bad days when luck seem to be saying no to them.
One thing about gambling is that, winning can never be forced, and so is losing, so, for the person who is experiencing a rather long and abnormal losing streak, it's better to stop than continue playing and end up feeling to bad due to the outcome of the game, winning in gambling was never meant to be a do or die affair.
That's why we must manage our finances with carefully because playing gambling doesn't not needs much money. We only use gambling for fun and not makes money but many people thinks that they can makes money from gambling. That's a wrong thought because they will not knows when to stops their gambling activity and will keeps playing gambling even if they already lose much money. They will not realizes that they don't have money left in their balance but when they realizes it, they will deposit more money to keeps playing gambling.
We can wins in gambling but that's not easy so we must understand that we don't have to playing gambling excessively because that can makes us confuse when to stops gambling. We will not realizes that the lose that we got in gambling shows us when to stops gambling.
