This is the most precious period in a person's life, the only one, and it is short-lived. If you understand how important this period is, you will feel that it is too short.So, how will he use the excess energy and abilities that he will never have again in this life?He will try to use it for those things that are useful to him when necessary.He wouldn't put his own stuff where thieves broke in, or in someone else's barn.To preserve it well, it must be placed in one's own hands and in one's own head.
