Leaving a little money for needs that we don't expect is of course very important because if we don't have these funds and choose to invest all the savings we have, of course this will make us unable to carry out investments well, because we cannot know the need for these funds. with certainty and if we don't have it when we need it, of course this will make us have to pay back what we have invested, both in terms of losses and profits. If it is in favorable conditions, of course this is certainly not a problem, but if the investment conditions we are in If you don't run it in good condition, of course you have to take it in a situation that is detrimental to you.
This is a basic thing that must be owned (must exist) in planning for good money management because after all, even if we have a large amount of money or income every month from the income we have but when money management is poor and does not anticipate basic things such as for needs and reserve funds then indeed income will continue to run out without leaving anything.
This is clearly dangerous because after all we cannot predict what will happen in the future that we will pass through and with the reserve fund that has been prepared from the start, we will indeed be more able to breathe freely when there are things that are not wanted considering the money we will use for other things is not used by unexpected needs because we already have a reserve fund as a form of anticipation of it.
Setting aside income to be used as a reserve fund will not make you hassle, instead it will make it easier for you because in the end if the funds are not used then it can be used as a better thing such as investment or other things so that it will not make you lose.
