Of course because money is important for our life our family life so we have to control our emotion if you don't then it will become big problem.
Money matters it is true so those who become greedy about making money and invest so much money without having knowledge will suffer lose, so if you get profit once try to wait for the next time, be sure you won enough but with time to time gambling, We just not to be greedy and control our emotions right on time.
As long as there is money involved,man in nature tends to become greedy.But in gambling,if you chose to be greedy,you will never be profitable in the end.As much as possible,we should learn how to control our emotions when gambling because if we let our own emotions controlled our minds,we will never find success in gambling.
I agree with your opinion. If there is any involvement of money, people are too tension. Just like me, I am also triggered when I bet even in a lowest value. I feel nervous when my bet lose or in the middle of the game, I predicted I will not win. Tensions will cover to our heart because money is valuable. But then, we should not involve our emotions all the time. Because we might lose if we will not concentrate to the game.
