Those people that are winning are really attracting us because we are thinking that we can be the same like them. But even it is human nature, we can do something about it. We just need to minimize our jealousy to those people that are showing their winnings so that we will not be attracted by them.
I don't think that there is a big problem in trying copy those that have profit in gambling. Well if it profit form casino games, then there is nothing you can do about it. There is nothing to copy, since it's based on luck, but when it's consistent profit from skill gambling, then you can try to learn from them. If they can do it, so could you.
