@Caek Islove 🍰 💖 We are already on the path to the pendulum swinging back home...
In any case, this is the advice I see being passed down as canon:
1) that each country (and by extension, each family, society being part of the family) be consecrated to the Sacred Heart of Jesus and the Immaculate Heart of Mary.
2) Never let your guard down and never be overconfident, never take for granted that your freedom is assured. Freedom is a right that each generation must earn and preserve like gold.
The role of the family is to educate at home: grandparents to children, parents to children and grandchildren.
3) Create a historical memory for at least 1000 years: familial, social, cultural, and national.
Regarding what to do and what not to do, teaching by example, explaining failure, why it happened, and its solution (success).
Generate the habit of documenting life and transmitting it orally and in writing, only that which complements and adds to the accumulated database.
One loses the day one thinks that there's nothing more he can do!
