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”
The most important thing in product design and development is “imagination.” While others developed laptops to fit the size of the battery, Steve Jobs imagined a laptop that could fit in an envelope. Then he pressured the battery company. If no technology was available in those days, he would wait. He traveled around the world in search of technology that matched his imagination. He envisioned putting a workstation (OS•X) in a cellphone and developed it for 3 years, but when Apple couldn’t deliver, he demonstrated it by connecting it to a separate workstation. It was a scam, but no one criticized him. - Joseph’s “just my thoughts”
