Answering this question is easy and a lot of people will tell what is in their mind about this topic but when you are experiencing this on the real world, you will be like a robot or an AI, programmed to win and have a fortune out of gambling, you will be having a hard time to control yourself since you're drive is to win a lot. I am not saying that all people are like this but most of them are.
lol yeah right. most people will just tell a lie and answer based on the topic only but in real life they cant actually controll their selve's and emotions when playing gambling. i know a friend thats good in giving advices to others but he cant actually applied that advices to himself , this is probably a good example to the op's topic and it can also be applied on gambling or any other things ofline or online.
although in my case i usually stop betting on gambling after i won a single bet no matter what the amount is, because im too scared enough to risk it again even though im still tempted to do it.
It's really a very difficult situation cause there will never be any definite global consensus to this idea, it has to depend on what your condition is, by that I mean how happy are you, do you feel content, or that gambler In you is more fiesty for more, gamble to take on more risk more gain, or let's go out and celebrate the earnings. I myself don't know what would I do, mostly bet again lol.
