Have you ever tried to save money for several months just to get something very important to acquire or accomplish but only for one unexpected expense to take out most of what you have saved, if not all? You have tried hard to limit unnecessary spending, you pay every necessary bill and try to save small whenever you can the suddenly something bad happens, your car breaks down and needs repair, medical bill comes up or something if emergency just happens. Before you know it, you are back to square one, where you started.
I have had a few personal experiences with this an thats why till date, i always keep an emergency fee with no label. That is simply want they things get out of hand and i need to quickly support myself and to do this comes with a heavy bit of sacrifice because to gain that stability where even when till go terribly financially you can still somehow survive it, you must make sacrifices with even the littlest things you do and how you spend your money especially when you have a set goal that you want to accomplish.
Like in my house, once i enter, if i am holding any cash, i put it in jar. Now the cash are usually transport changes or when i withdraw and i get a change from buying something and i still have my normal emergency fee with no label. Now that jar at home, i know how many time it has saved me from situation where i have no network but i new cash urgently. so all these just came from my own experience with finances, it just something i still do.
