As you are from humanities, there is a little chance that, you have ever dived into this field. The world of Finance.
Money, is just not a commodities or tool for exchange, in this modern era it spans our entire life, plays a crucial role in everyday life. Understanding this will get you ahead of 97% of world. And will eventually lead you to fincial freedom.
For that I recommend you:
There is also a series on Netflix named "Money explained", I have 5 episode and address few topics like loans, credit card, old age retirement and more and in a subtle and elegant way.
