When you have a feeling that today will be your bad day in gambling, that means you are in a bad mood and it is better to stop till you can get your good mood again. Tbh, when we are in a bad feeling, then we tend to make some decisions badly too. Clear mind or good mood is something that take a big role in our gambling actions.
Basically what I was thinking, sometimes the most profitable thing is not to lose money. The other route people have recommended that I agree with is to reduce size but not everyone can do that and continue with the same attitude and enjoyment even as they normally would. Step away for a break is massively under rated in terms of money control and just not playing tired, drunk etc. all going to save money very probably
You will not be able to attract luck if you think you have a bad day because you will not be aggressive.
When you are lucky, that's the time that you should be very aggressive but always with limit since winning does not happen
all time time, so take chances on your lucky day.
