Play for fun.
Don't chase your losses.
Stick to your Limits.
I agree these things that we need to remember in gambling.
We must know that gambling is a place for fun, it is not a serious place to look for income. So, fun is the goal when we are gambling. If this part is gone, we must be aware that we are no longer in an healthy gambling.
Yes, chasing the losses is a very bad idea. Every gambler must understand that doing many attempts in gambling doesn't guarantee to win many times. So, we mustn't assume that more playing will increase the chance for winning. Chasing the losses is done by someone who still doesn't understand what gambling is.
It is a must to use the money that we really allocate for gambling. Never try to use the money for main necessities, it will ruin our life. Since gambling is just for fun, we don't need to serious spending too much money.
