Just be relaxed and think rationally and then you can make the correct decision
This is the part where it seems the easiest but the hardest to achieve. When you start to lose in a row, you will tend to believe that your winning is going to come soon. This will be a popular gambling fallacy because regardless you win or lose in the previous round, the chance of you winning in this round does not change and you are in fact in an disadvantage. However, people tend to chase their losses and end up losing even more.
Yeah,
People who come after their loss amount of money tends to always lose, or lose more than what they are after for,
and also I believed that even you've win or lose in a row, the chances of losing and winning doesn't change at all.
Gambling is mostly based on luck, and we should accept it.
