Almost most gamblers think like that; that's why others think that gambling is a job, and for others, it's just their hope to rise in their states of life.
In this aspect things can happen in different ways of seeing things , first if one as a Person Commits only to venturing that things have to be done for work, it is something bad when it is for a casino I don't see it that way, unless I I worked in the casino, but that is no longer in the game, now I hope, the only thing that many focus and take refuge in is that they can do it well, I am one of the people who believe so, we must have positivism and hope, but On a personal level we must Combine that hope and Positivity with the reality of things, that is why we have to focus on doing things well, I would recommend seeing the casino as a way to do things better alone Allocating a part of the money that has been assigned to it lose.
We need to be practical as what you mentioned, you need to be positive but also we need to make sure that we are careful in terms of our finances, being rich or poor in terms of gambling needs good self control to avoid making big mistakes and lose all your money from your savings, but as long as you have that good control whatever your position in life there's a big chance that you'll be able to avoid losing more than what you can afford to lose.
Though in most cases, rich people is the one who can control as they know how to value their money and they are keen in keeping their setup in terms of controlling their finances and avoid overspending of their balance.
