There are a number of different reasons as to why a person should learn about personal finance, but it is perhaps understandable that most people can not see these reasons for themselves. Personal finance is a difficult topic to learn about and for that reason a person just naturally tends to shy away from it, making excuses in an attempt to avoid having to learn about it. Well, personal finance is extremely important and here are some reasons why.Money FlowIf you understand personal finance, then you will understand your money flow a lot better. There are a number of people that muddle through life paying their bills and their mortgage payment with the money that they have and then spending the rest of it or maybe letting it sit in their bank account. These are people that have no idea how personal finance works, so even if they end up making the right decisions they are doing it through luck.While there is nothing inherently wrong with this particular approach, don’t you think that you would feel much better if you knew exactly what was going on with your money flow? The old saying is that knowledge is power and if you know about your money flow, you arguably have the most important individual power that exists in the world today.Uncertainty and FearHuman beings as a species have an irrational fear of uncertainty. In this respect, we are no different from any of the other mammalian species walking the planet, because all of them have been conditioned through thousands of generations of being eaten and killed to be afraid of what they don’t know. Uncertainty and fear therefore go hand in hand and when they do this in relation to something as important to your basic survival as money, the paralyzing effect that fear can have on you is something that is not even pleasant to think about.Compare this situation however to a situation where somebody knows about how their money flow works and understands their entire personal finance situation. This person is not a person that is likely to be afraid, since there is no uncertainty involved with their financial situation. It is a lot easier to be afraid when you have no idea where your money is coming from and where it is going.UtilizationIf you truly understand personal finance, then another thing that you definitely should understand is utilization. A person that does not understand or appreciate personal finance is a person that is unlikely to save a lot of money, instead spending whatever they happen to have left after monthly expenses on entertainment and impulse purchasing. While there is nothing wrong with being a consumer on this level, it is something that might hamper you later on in life when your income begins to dry up and you realize you have no prospects on the horizon.If the person does not spend a lot and does not understand personal finance, the same thing could happen. While the money in your bank account is available to you instead of having been spent on something impulsive, it is still not being utilized to its fullest extent.Only a person with an understanding of personal finance would know that money being saved should at the very minimum be placed in a high interest savings account and later on should also probably be invested in things that yield a much higher interest rate. This difference in understanding and ultimately in utilization comes specifically from an understanding in personal finance.
