Totally! People should think before leaping into the action themselves, emotions, good and bad, lead to consequences that won't be pleasant to remember. A win is a win, and it should be noted before continuing and making a decision on what to do next.
Yeah , because when one is losing sometime, they don't usually know when to stop because all they want is to get what they have loss back, same thing goes, when they are winning they usually just want more. Well to me as a gambler you should try to have some principles like know when to stop . Because just as you said a win is a win , despit how small it may seems. Because better to win little than to lose more due to finding big win.
Yes and maybe I would say that someone you said is someone who has entered the addiction phase where they simply always feel dissatisfied with winning so they apply greed and when they lose they are unable to accept the fact of the defeat, meaning maybe I would call them losers who only want to win but don't want to experience defeat.
It is very clear that this is the wrong approach and mindset in gambling, because after all it is a fact that actually winning is nothing more than a probability or "possibility" and defeat is a "part" that can never be eliminated in the game, meaning that winning and losing are 50-50, you can win a large amount but you can also lose a much larger amount. In the end the best thing is as you said that the ability to stop at the right time is a must for a gambler, but to be able to achieve this ability you must first justify everything from the beginning, meaning you must first change your perspective on gambling in the right direction that is in accordance with the facts about what and how the activity actually is.
