When you are in a situation which you do have a family and the expenses are really that big due to lots of children then it would really be that hard to make up some savings.
I do know someone who is really that reliant with his crypto earnings which is surprising and its been several years on which he had able to make money still despite on having no job
physically.It might really sounds easy to say that saving up some one third of your income but its actually that hard for it to be done when you are on such situation.
Unless if you do have other sources of income then it would really be able to patch up.
Other sources of income can give you that chance to save more, but the concern of having too much expenses means that you won't be able to work with it, unless you can really take things seriously and plan all your expenses, most of the time there are emergency that you need to use your save money, things that is not part of the plan but it happen and there's nothing that you can do.
