Every gambler will have have to choose what they take gambling as , but as for me I will prefer to choose gambling as an expenses, if I choose gambling as an expenses I know I have to keep little money that I can afford to gamble with. It is a wrong idea to make gambling as an investment because one may decide to invest so much money in it and even if their is no winning you will just be having hope to get a win bot knowing that one is making a mistake.
Considering gambling as an expenses will actually help control how well you gamble especially how much you spend gambling because things we consider expenses are such that we don't really expect to yield back our money after we may have probably lost it but if we see it as an investment then the chances are that we would not consider controlling how much we pit into it because we believe it will still give us returns and the logic would mostly be that the more we invest the bigger the returns but this in most case isn't the case so keeping a different mindset to it like this is most likely going to help a whole lot.
