If you don't want to lose money, don't gamble.
The sad reality is that some gamblers does not see the risk of losing, they are very aggressive to gamble and expect to win big with a small money to risk. Failing to understand the strategy to win in gambling will result to a bigger loss especially if you lack self discipline.
Successful gamblers don't take things in a hurry, they are very patient and understand that in order to win long term, they should be consistent and take it slowly.
The reality is we have different mindset as a human but everyone needs to be discipline in order to enjoy gambling, regardless of the outcome.
