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 agree with you, most of the time we just suffer because we do not apply to our self the best practice's .We must remind our self that nowadays the goods are really expensive so for us to survive we have to control our self that we shoudn't gamble our money . If you cant stop it in an instant you can do it step by step and limit yourself until you finally removed it in your life. Limit, divert and look for alternatives to replace the gambling habit.
