Take a break after experience losing streak can make our emotion are colling down i think this is good act because when we can control our emotion we can thinking more realistic and didn't aggressive to gambling to recover our loses so this behaviour i think it's necessary to avoid unwanted things such as gambling addiction and for me i didn't gambling quite often so it's rare to me to gets losing streak but usually if i experience something like this i will stop gambling temporary and doing other activities
Yes, I think if you start to consider the psychological aspects of gambling, specially if you are losing, I think it's a great way to do some kind of circuit-breaker to simply stop gambling.
Now, it's probably easier said than done, since it's basically an addiction. So, I think the best is to keep yourself busy with something productive. That way, your brain will not be able to think about gambling, since on human brains there's only one thought allowed at a time. Try thinking about two different things, you will jump from one to another, but it will be impossible to focus on both at the same time.
So, that's kinda how you could break free of addiction.
