If you care about what people say as pertaining what you do you'll end up with their own decisions but in the aspects of gambling I would say when people's opinions should matter to you will be when your gambling habits is getting out of hand and then someone had to come in to say hey this way you're going isn't good and profitable so back off, when this is the subject of the day should be when you follow suits, I know of a truth some don't like anyone saying or contributing to anything that pertains them gambling but for me I don't care what people say cause I act responsibly with my gambling habits.
I very rarely notice that someone says something about me, or I simply do not pay attention to it. What I do, what I wear, where I work and everything else is only my business, my well-being will not change from someone's opinion, I will not live better just because I will try to please others, and if they do not like something about me, then it is not my problem. I perceive someone's opinion about gambling in the same way, I know that there are many people who consider gambling to be something bad, I will not argue with this, everyone sees what he believes.
This is only true if they are not our loved ones because they may just be jealous of our lives but if those words come from our parents or wife, we should not ignore them. Because they just want us to get better, they don't want us to fall into the trap of addiction or out of control gambling . We should take the time to explain to them and listen to their contributions to improve ourselves because sometimes there are things that outsiders see but insiders do not realize .
But if you are so stubborn that you ignore everything, even what your parents or wife say , and always think that what you do is right, then it's okay . But you will soon find yourself in a similar situation where your wife and children do not listen to you and ignore all your advice . So in my opinion , it depends on the person giving the advice and we need to be flexible in how we respond .
