Traditional education taught that human economic development progressed from hunting to stock farming and then to agriculture. However, the only real difference is that stock farming is an economic method of obtaining food by domesticating livestock, while agriculture involves domesticating plants. Therefore, this three-stage development theory is no longer accepted. Instead, the development of human civilization can be seen in the evolution of transportation. To understand the nature of how the world changes, we should observe the development of transportation. The increasing speed of movement is the main evidence that society is changing rapidly. - Joseph’s “just my thoughts”
Umbilicaria esculenta is a kind of mushroom. To pick this mushroom up, a picker must climb a high mountain and approach a dangerous cliff because this mushroom is growing up between rocks. Therefore, umbilicaria esculenta is more expensive than other kinds. One day, the TV show "Korean's Dinner Table" on KBS 1TV showed an episode about the mushroom picker and his old mother. "Don't sell this mushroom at a high price." said the mother, because this would be sold at a higher price, many pickers would die from over-picking even dangerous situations. We should deeply consider what is the mission of our businesses. - Joseph’s “just my thoughts”
