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 wall feels uncomfortable and unclear primarily because it is vertical. Its thickness and height are not the key issues; what matters is the slope. If the slope is mild, anyone can ascend it, regardless of the wall. Thus, it’s advisable to steer clear of climbing walls and to do hills. Life’s challenges stem from the endless cycles of rising and falling rather than simply from the effort of climbing upward. - Joseph’s “just my thoughts”
