When you are going to gamble then the first thing that I think about is making money because that is the reason why you make money with it.
But I can also see why some people have fun with it.
So you're on good way to addiction. Gambling should just be fun. When you start playing to earn money, emotions begin to rule over you, and usually you lose..
That is why you just need to control your emotions as you gamble. Especially if you are making gambling as your main source of income, you must be cautious on your own emotion. Just able to have self control of your temper. And don't let your emotion control you especially when you are losing, just keep calm and enjoy it.
