... I dont see how emotions make us lose in gambling faster when we all claim luck is the main thing in gambling. When we lose its bad luck and when we win it is good luck. My point is, poor decision making, using emotions to gamble can result to anything, both positive and negative.
Well, being too emotional can drain your bankroll very quickly. So it makes you lose in gambling faster, no matter how lucky you might be in the early bets. In the long run, gambling always leads to the same outcome, the house has the edge, and you eventually lose.
While your decision making will fully control your bankroll, how you manage your bankroll determines whether you maximize your chances during winning streaks or minimize the damage during losing streaks.
