What rules of ancient Greek upbringing would you like to follow, and what not?

Can be seen on the example of the traditions of Laconia. It should be borne in mind that after giving birth, frail, sick and ugly children were thrown into the abyss. In childhood, the upbringing of boys and girls was not particularly different. They had no luxury. The cradles were hard. When the boys were 7 years old, childhood ended and they were sent to military camps. There they were trained to survive. Principle: failed – died. For this reason, the Spartans were considered physically fit and healthy. Few people now think about the fact that a significant number of children died before the age of 10. The strongest survived. Future warriors were fed very poorly and were almost forced to steal in this way. I really don’t like all this. But they were taught to fight with all available types of weapons, as part of a unit and on their own. It is worthy of respect. The Spartans did not particularly bother their offspring with various kinds of sciences. They were taught to be laconic and witty. I believe that the lack of education is already a problem.

One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
