1. WHAT IS YOUTH?

Your grandparents are about 60 to 80 years old. Those between ages 40 and 60 are middle-aged people. Those between ages 20 and 40 are the "youth." (96 - 238)

Which period is the most important period for people? It is not during adolescence. The most important period is when we pass through the period of youth to middle age. In other words, the most important period is between the ages of 20 to 40. From the age of 20 until they reach 30, people form the foundation to start functioning as human beings. During this period, people have to lay a firm foundation for their retirement. They also need to lay a foundation in their environment so that they can go forward with a clear goal. Those who are unable to form this foundation can only become insignificant or ordinary people when they go on to age 40. (22-314)

Is God busy now? Then why is God busy now? It is because human beings cannot live on this earth for such a long time. We cannot live on this earth forever. You people will soon pass the period of your 30s and go on to your 40s.

When we look at the entire life of a person, when is the period that he or she can best display their ability? It is between the ages of 20 to 40 or 50. During these 20 to 30 years is the period of growth. After the age of 40, you will start declining from that standard. Those of you who have gone over the age of 40, look at your physical body and think for a while. Kwang Yol Eu, you are 43, right? (Yes.) Don't you feel different from before? (I feel tired.) Tired, uh! A long time ago, no matter how tired I was, I was able to recover after sleeping a few hours. But as I grew older it took time for me to recover from fatigue. Even those who worked 10 hours a day a long time ago will experience a decrease in the number of daily working hours, year by year. You will feel that your working hours are decreasing by one hour every 3 years. If you think like that, after 30 years, your working hours will shrink by 10 hours. If your working hours shrink by one hour every 3 years, then they will decrease by 3 hours after 10 years and 10 hours after 30 years. Therefore, if you worked 10 hours when you were young, after 20 years, you will not be able to work.

By the time you reach 70, you will be unable to work any longer. At that age, you will only be able to take care of things. In other words, you won't be able to do pioneering jobs or something new and constructive. From this point of view, when you think how much you can work for the providence, you should know that you will feel sorry forever. (33-185)

When spring comes and we look at the whole of nature and see flowers blooming and new leaves coming out, we come to think that spring always comes after winter is past. We also know that after spring, summer will come. Therefore, we know that spring days are the preparation for summer. The four seasons make us think this way, but we can also see the same thing in human beings. When we look at young people, we experience something like a spring feeling from them. We know that after youth a young person will go on to middle age. We also know that a person will complete his or her life by going on to old age. When we look at our life from one age period, we learn that we go on to the next age period after a certain time. (66-85)
