That is the reason why we shoud be financial literate. With Financial literacy, there is a high possibility that we can achieve our desire and have better future because it can be the key to do it. It help us understand our own money and what we can do to improve our finances. It also teaches us how to save and invest and to protect our capitall from financial risks.
For me if your goal is to make more money, then it is better to invest it rather than to sit the cash in bank. I think the interest in our country is just 0.685% to 1.231%. I'm taking about yearly so always consider the interest before you put your money in bank. It is a opportunity cost for me so If I have that money, I'll put the 10% in bank for petty cash then 90% is for investment including investment in myself for me to become financial literate.
