Sometimes, we don't need to listen to what other people say because their comments to you will become your basis in yourself,it's hard to listen and trust what other people say because we don't know what their intentions are when criticizing you, their judgement may be good or bad but at It's better if you will listen to your family and closest one who knows you better and wants to improve yourself in life, for real.
Gambling can either been seen as negative or positive activity, it depends on a person's point of view. Gambling is an open activity in which anyone can participate without any pressure from others. Besides, this is a free world, and I've worked hard enough to pay my bills, so I won't tolerate any type of abuse from anyone; after all, I'm not looking for an entitlement post in either religion or where I work. We are citizens who work sufficiently forceful to ensure that we create our primary income for ourselves and our families, and we do so while simultaneously creating change for pockets.
As long as you know yourself why you are into this gambling activity, there's no reason to be guilty of.
Because people will always have something to say, no matter what. So if you are confident about yourself, then there's nothing to worry of.
Worry if you are loaning the money and spending your basic needs, and you have no financial back-up where you will end up destitute.
So in this particular subject, so long you are not bothering anyone because of your gambling activities, there's nothing to be concerned about.
Gambling is considered as a negative activity to do as there's a high chance of losing money, and that is the norms that people know about. It is already expected that people have always something to say it's either they care for you or just want to feel better for themselves by just simply saying that your habit can ruin your life. I agree that if you know to yourself that you are a responsible gambler, then there's nothing to worry about what people say because you to yourself know that you can manage the risk of gambling where it can reduce the possibility of addiction, financial issues, health, etc. Thing would be different if you are already married or have a family cause you need to hear their concerns.
