It is better not to put your attention too much on the potential win but everything depends on planning. Even if you think about the potential win but you plan well, you can still discipline yourself to gamble what you can afford to lose knowing that desperation will not help you achieve the target. Without putting mind on the target, there will no be much motivation to gamble after losses happen. So the target is a good motivation but it should not make us go beyond out budget to gamble.
