Gamble only with your free time and don't fall for your emotion, it will lead you to lose control as you win.
If you're going to gamble, do it for entertainment, not for profit.
Correct.
Gamble only for entertainment as if you are not expecting some wins but if you win then be thankful.
If you don't want to suffer, better to play this way, enjoying and entertaining yourself, considering that the amount that you will spare can be forgotten after, always think for positive side and if you win and you are already satisfied with fun that you've got also consider to quit and enjoy with some earnings that you've got that's an additional rewards.
I wonder where some people actually got the notion from that gambling can make them extremely rich and then forget the side where the losing sides are usually more than the winning sides.
As long as this mentality is not in check, people will keep falling into this trap and then before they could even realize it at all, they have gotten so addicted already. It is one thing to lose and accept your fate, and it is another thing to win and accept your luck without pushing it further, anything out of these categories is bound to flop, big time.
