I hate to say this but today is the last day of summer school. During the summer we learn about Demand, supply, wise buyer and banks. I remember when tow guys form wills Fargo bank come to tell us information about the bank. They say that people start using bank in the middle age, people from that time they use gold, silver , and paper to trade. I was so amazed by that and I never know about it until that time. Personal finance is very important to me because it help me manage my money properly, like the money i need to save, spend on something.
