Lets assume all of this is all about gambling and we separate business talks since we are in gambling section but people would really be in harmful condition if they don't think what they are doing so aside for taking the risk they should have brains to use so that they can try certain strategy that can help them win. Gambling without any aim or target is not good so people should set something that they think can satisfy them.
A gambler without an aim is mainly risking his time and money. He'll stop gambling is the money runs out. The risk as stated by Op, is not something a player can engage into with no prior target. One can't just take a risk for no reason. In any venture in life, we ought to take risks. But what is the aim of gamblers who take frequent risks and don't achieve their goal? Risk is to be taken once a while, not all the time. When we are taking risk in gambling, it has to work with our instinct. Personal speaking, when I'm into a game, at some point I'd feel a bit sure of what could be my next outcome, I seize the moment for some risks. Although it doesn't occur to be as I presumed, but sometimes I win some funds out of the risk. Gamblers are meant to have strong observation of the game they are playing. Such that whenever they deem it right to take risk it won't affect their bankroll. Risk should be taken, not often, once a while.
