One of the key principles of money is ‘opportunity cost.’ It means that when I buy something, I have to give up something else in return. We think we buy because we need something, but we often forget that we could buy something else instead. We rarely consider ‘opportunity cost’ when making a purchase. We do not compare other values against our needs. Buying something means giving up something else, but we often don’t realize it. When we spend money, we should also consider the ‘opportunity cost’; yet, in reality, we aren’t trained to do so. By making a purchase, we bypass the value comparison that may not offer any additional benefits. Maybe it’s because we lack knowledge, or perhaps the idea isn’t appealing. - Joseph’s “just my thoughts”
As a classical composer, Beethoven was the first to assign the work number 'Op.' to his works. Music scholars numbered the works of other famous classical composers after they had passed away. Beethoven believed that his work would be passed on to future generations, and he made it his responsibility to do so. Therefore, uncharacterized works were not given an 'Op.', leaving him with fewer works than other composers. This attitude influenced other composers and made them responsible for their creations. Since then, of course, the number of works by composers has decreased. The responsibility of one person can affect a generation and beyond. - Joseph's "just my thoughts"
